A simple HTML-based web page design is to be modified to incorporate
CSS, typically.  The existing page is used to display the details for
the sought-after modification:  http://www.mundi-causa.org/modify.html

For $100, do you have a question? Perhaps you might take a look at
hiring a web designer, or you might be one, so look at some content
management software from opensourcecms.com. Or just use FrontPage...

Ack. Who is the intended audience of your link? It is a very formal
read, but "sounds" like it is something to be communicated to a
specific entity.

Thank you for your comment.  That was a superb link you offered.  As I
understand that CMS site, I can develop a web page/publishing 
application using opensource and already packaged applications that
can be modified.  My experience is that I make a project out of
creating an application rather than advancing my prime project, to
publish.  Since that has proven to delay me rather than help, I used
this venue for seeking help on the master page I linked to in my
question.

As to hiring a web designer, I thought this was how I can best find one.

There is a hierarchy of intended audiences, starting with (mainly)
bright professional persons who are concerned with prevailing and
worrysome trends in societies everywhere but see no systemic solutions
to make them less worrysome.  Through collaboration with such persons
in areas to be presented on that site, far less formal learning can
then be offered to other concerned persons who have more narrow goals
related to their personal lives.  Hope this helps - it is not easy to
discuss that more constructively here.

I used an address from your suggested site to point them to the
question I posed - perhaps they can apply their skill to offer the
solution I seek.  Many thanks again, crythias!!!

Glad I could help, I think?
I have a few questions, if I may... 
Are you the owner of the mundi-causa.org site, and did you write the
modify.html page?
Somehow, I am trying to figure out if you are a third party interested
in fulfilling the needs of mundi-causa.org, specifically
mundi-causa.org's modify.html page, or are "of" mundi-causa.org,
trying to find someone else to fulfill the needs of
mundi-causa.org/modify.html. I would like to, if possible, separate in
your response the intent of the site's CONTENT from the intent of the
site's DESIGN.

Also, I'd like to know to who (generally- is it the people who might
contribute content or the people who run mundi-causa.org?, not
specifically- names aren't valuable to me) is represented by the
pronoun "them" in your statement: "I used an address from your
suggested site to point them to the question I posed"

I guess the last bit of questions are... who contributes content? Is
there to be one webmaster or is this more of a collaborative site
(like a WIKI)? Do you need/want a bulletin board/forum or is there
going to be a webmaster who posts based upon email sent to the
webmaster?

I think I understand that you also want to separate the work of
content from the work of design. Based upon what I've read regarding
the people who are Google Answers Researchers (and I am not), their
contract prohibits direct contact with  people on Google Answers.
Since I'm guessing you don't want your logon information public,
perhaps there are other resources.

Thank you for your comment and continued interest, crythias.  
I was the principal founder and driving force in establishing Mundi
Causa in 1997.  It is not a 501©(3) and for IRS purposes is treated as
a business, although it is a membership association incorporated in
Calif. With an EIN number associated with my personal taxes.  I
deactivated it soon after formation for specific reasons.  In
principal it had to do with realizing the need to document the body of
work I performed prior to its formation.  For over two year I am
trying to work on the documentation and instead wasted much too much
time on trying to learn HTML and CGI, in addition to other
interferences.  The Society will become active again,most likely this
year.  There is no second or third party involved with the task at
hand.

Re Content contribution.  The involvement of collaborating persons
will take place in a managed manner, but NOT by using the ?modify?
page, nor blogs.  It involves multiple work groups, but only after I
have presented my work product first using the 'modify' page.  How to
collaborate is an entirely new issue to be resolved, although
procedurally it is well defined.  Those who will contribute may come
from professions such as law, Government, some from academia, from
organizations involved in social change, environment, economics,
financial/monetary systems, etc.

Re pointing ? those were people associated with the website you
mentioned.  I asked them that since I was given their site, and
learned that they perform services, to look at the modify page and
make recommendations, if they were so inclined to do.

It intended to work with Google researchers since they DO perform
actual services, as I have seen.  They communicate via comments.  I do
not know what other resources there are.  I see well meaning people
hammering out websites, but they pride themselves more on appearance
or their artistic design skills than on designing against certain
specs.  I know codesmiths exist, I know they advertise, and some
designer?s kitchen table may come across as a skilled design firm.  I
am unable to evaluate their skills, and under Murphy?s Law, the
service fees will keep climbing.  Thus the question posed for a stated
fee and for a stated service.  Looking at prior Google jobs done, I
believe that the fee I offered is fair, given what I have seen that
has been provided by Google researchers, very often for substantially
less than what I stated.

If you see anything that will help me to achieve my objective, Google
researcher or not, I would greatly appreciate your further comments
and suggestions.  I hope this helped, that I was responsive to your
last comment.
