I know you know how to write code, but, to save time you can fill a few data fields and upload some pictures. It autimatically submits to Trulia, Google and some others.

You then copy and paste it right into craigslist (it will link you to it) and it reposts your cool looking flyer. Much better looking than a regular craiglist post...
