This is an easy job taking perhaps an hour, or two.
We need two bullet-proof Craigslist Posting Templates as follows:
FIRST:
600 X unlimited height
banner
right copy column including "specials" table centered 80% five cells
left image column
footer
SECOND:
600 X unlimited height
banner
right image column
left copy column including "specials" table centered 80% five cells
footer
Each template is centered
We will provide the banner and images in addition to the copy.
The proof will be whether the two templates maintain their specifications upon posting into Craigs List.
