Here's the deal, a programmer friend of mine has already successfully added this feature to his site, sailob.com. the problem is that his server is .Net. He has given all of his code. I need it done in php. It needs to be portable, as I am a front end developer and have had a few requests to add this feature to my clients' websites. It will also need to be set up so that I can easily style the layout with css (adding in classes? idk).
Please let me know how much this would cost if i provide the .net code, as well as how long it would take. Thank you.
