Could someone please translate the following, from English to Korean:

Thanks for all the hard work.
Best wishes and continued success.
Team Postal.

(Alternate last line could read - United States Postal Service)

Jun 2005 - Jul 2006

An acceptable answer should include the translation in Korean text (A
link to a prepared document, preferably in some type of picture
format, so I won't have to load a Korean font set, is perfectly
acceptable). Also due to differences in culture, if
there is a better phrase that could be used (a more traditional Korean
phrase, on wishing someone good luck/fortune when they leave a job),
that, would also be acceptable.

I'd also like a breakdown of the phrase, and how it should be placed
on an engraved metal plate. In other words, I don't want to break up
the phrase at the wrong point, making it look incorrect to someone who
can read Korean.

Example:
(Correct)
Thanks for all the hard work.
Best wishes and continued success.
Team Postal.

(Incorrect)
Thanks for 
all the hard work. Best 
wishes and continued 
success.
Team Postal.

Also a breakdown by word as to the meaning. Example:

(Phrase)
^%# &(+~ @@)

(Translation Breakdown)
^% = Have 
# = a
&(+~ = Nice
@@) = Day

The dates can be in Chinese calendar format also. (I think that is one
of the more traditional calendar formats used in Korea, but I could be
wrong).

So to sum things up, I am looking for:

A phrase that can be used to thank someone for their work, and a wish
for continued success, in a traditional Korean format.

Thanks in advance!
