College Book Student Resell Service iphone App - repost

Using data from google places (location) and app data from users (ratings) an algorithm will recommend the user to the 'best' place for students to post their gently previously used college textbooks and career tools for sale among students for more than they would ever get from the college bookstore. Students create account for free then post smartphone pictures of books/tools/and best contact information (email/text/or cell phone) them to purchase the item. No shopping cart necessary as terms and conditions should clearly state payment due at time of exchange. This is a proof of concept with a very basic GUI and minimal back end. If it works and you do a good job, there is much more to come.
