This job is easy, if you are experienced.
the site im looking for is a combination of Ebay and Facebook together.
Here are the features im looking for:
you can sign up for free. you can post an ad to sell your items using text and/or video. instant messaging, video chat, tell a friend script, incorporated with paypal, or other payment process companies.
a lot of features of ebay, and we make money when an item sells, and providing upgrade features.
if you know how to use amazon's ec2, it would be a plus.
Thank you for your time and help.
