I'm a web developer. My potential client is in commercial real estate. His properties are on Loopnet and Craigslist. They are not in local MLS or anything. I assume there is no way to pull his listings from Loopnet (and certainly not Craigslist I would think) correct? In other words, there is no feed like I do with my non-commerical client where I just setup an IDX for them?

In this situation, what do you other developers do to showcase the client's commerical listings on their site? Do you use some listings software and make them enter it into the website?
