Custom Store and Models Portfolio Re-Design Homepage

We are in need of someone to modify a Wordpress template to add some more functions to it. THE STORE PART. What is needed for the Store: -The main concept of the store is to sell and buy books, it must be associated with the ISBN books database. The database have to include book name, authors , or title. (SIMILAR TOO AMAZON or [login to view URL]) -Customers can post, edit and delete their products on sale. -Customers can leave feedback for the products. -Payments are to be done specifically with Paypal, Credit Cards and Pickup Personally (Cash). THE MODELS PART. What is needed for the Models part. -Aspiring Models should be able to post their profiles info, upload their pictures and edit their profiles aside from normal Subscribers. -Model of the month would be selected by users voting for their favorite one. So there must be a voting system for the models to determine the winner. -The winner is going to have a featured part in the homepage. Each winner will be added month by month. All this must be compatible with buddypress. Please follow the design that the page already have. Our last developer messed up the layout of the homepage so that needs to be fixed as well. All other information will be provided upon contact.
