Facebook App Pro Needed

I need a basic facebook application that would basically 'embed' an oscommerce store in facebook. I am considering 2 options and am open to suggestion/discussion. Option 1 would be where the app simply fetches the data and presents the items, price and a 'more info' button that simply links to the existing oscommerce product page. Option 2 would be where the app is a self-contained version of the cart. Items would be presented and purchasing would take place from within the app and not necessarily link back to the app. I'm guessing that due to security issues and various other complications, Option 1 would be the logical approach. So the app should simply add a 'shop' tab to an existing facebook page and then display products fetched from an existing osc store. A couple of examples of what I'm wanting are: [login to view URL] [login to view URL] [login to view URL] Depending upon which method ends up being used, budget may be adjusted/increased accordingly. I'm only interested in dealing with someone who has done this type of work before and can provide knowledgeable information. Generic replies like "we can do it" or lists of sites done that have no relevance will simply be ignored. Respond by letting me know any similar work you have done and what your plan would be. Thanks!
