I put my life savings into creating a company.  When I ran out of
money some VCs invested and took majority interest.  They just turfed
me out with no golden handshake.  I have enough money to live for 3 to
4 months.  I have to sell my timeshares.  I have one timeshare in Maui
and one in Myrtle Beach, SC.

My son says he has looked and most web sites charge 30-40% commission,
fee/month or fixed fee.  No idea how effective the many sites are.  I
paid $5,000 for each timeshare, but I do not how to price them for
sale.  How should I go about selling them quickly and price
effectively?

(1) Do some thorough looking at a website called "TUG" -- TUG stands
for "Timeshare Owners Group".  They are at www.tug2.net.  There is a
discussion forum, which is free, but you need to obtain a password. 
Be advised, however, that even though the group is ostensibly for
owners of timeshares -- in fact there are plenty of sellers who read,
and sometimes post.  It costs $15 a *year* to join.  If you join, you
can post your first ad for free.  Each one thereafter costs something.

(2)  There is a "bluebook" here:  http://www.triwest-timeshare.com/bluebook/
It has a search engine for many MLS (multiple listing system) listings
of timeshares.  If you plug in the names of your timeshares, one at a
time, it will tell you how many are currently for sale (through that
system), and how much is being asked.  Be advised that timeshares,
like houses, are almost always subject to barter.
