I need a site very similar to booksdeal.com. In addition to a shopping comparison feature for books, i want users to be able to sell their own books through the site, once they have signed up. In addition, I want users to be able to select the university attend in the US. The site must look simple, but good.
A database for users and the books they are selling
security (Captchas where necessary)
Shopping comparison feature
I would like a version of the site to be available on smart phones, please indicate on your bid the cost of 1. a website designed for a regular computer screen, and one designed for a smart phone (Iphone, BlackBerry, etc)
