Classified Ad Poster Software

I'm looking for a programmer to create a classified site ad poster, where users will write ads, select categories, check off what sites they want to post it to, and hit "submit" to have their ad automatically posted to several classified sites at once (I realize that they might need to fill out captcha forms or something that would all pop up at once). In addition, the software should be able to allow users to setup multiple "campaigns" (different ads in different categories if they want) where they can set timers for how frequently they want to post the ad. It should also allow for the same ad being posted to multiple cities, easily integrate it to use with different e-mail addresses, and an easy way to slightly modify each of the posts (by hand is okay, but perhaps have a basic template they can use). It would be a plus if it integrated with any type of proxy list. The idea here obviously is to save time posting ads to multiple classified sites in multiple cities at once. [login to view URL], [login to view URL], [login to view URL], and [login to view URL] would be a must -- any others would be nice to have too. Any features to make this easier would be appreciated and paid well for. The right programmer will also get a chance to take a cut on top of their pay and potentially get offered a full-time work-at-home position if they wanted and if things worked out well. Take care, Brian
