Custom IDX Real Estate website programming

I need custom programming so I can download from my MLS/IDX provider and then upload to my webpage once a day custom information. Or if FTP is available we can pull the info that way but still investigating that option. Currently my IDX provider ([login to view URL] and [login to view URL]) only shows Active homes for sale but I want to also add homes that are pending a sale and recently sold to my site. I also want to add to the map available home rentals from craigslist ( see [login to view URL] for an example) Also need a feature that when users look at one house, other houses pop up that are similar. Think of [login to view URL]'s " If you like this house, you may also like these homes" Please open message board for more details and links that will explain
