Online book reader embedded into a website.

We have an online bookstore where people can buy book (printed) edition, but we also want them to be able to buy the book in ebook format (pdf or epub) and to be able to read them inside our website. We already have the website ready and it is fully function expect for the part of reading the books. We have made the design of the Library section of our website where people will go to see and read there online books that they have bought from us. We have all the books in pdf files. The person that we are looking for to work for the project have to do it in time and also to be able to work with the existing website data which is 100% pure php/mysql/js. We will help him as much as we can to understand the project and the code that is already existing. We need the person for this project to be albe to: - edit our existing code so people can order ebooks as well (shopping card) - create the module "Library" (we have a working design) where people will go and view there books and can click on one of the books and start reading it - create the reading module in our library... we want something like this: [login to view URL] with core features: we want only one page at a time, we want the pages of the books pages to be generated randomly so there is more security so people cant stole the book, we want a system that remember where the reader have stopped reading and when he/she come back to open the book at the same place, we want bookmarks as well. We will give you a working copy and db of our website. We expect you to do the project in no more then 3 weeks.
