E-commerce website for

I am looking to create an e-commerce website similar to notewagon.com. Its an online marketplace for students to buy and sell university notes and other revision materials for (real) money This is what I am looking for in the website: -When user opens the website, they will have to sign in to view the content of the website. -Once the sign in, they can choose their courses easily from a menu containing thousand of courses -Before a buyer can buy the materials, they should have the option of previewing 25% of the materials posted in a blurry version - Once someone buys the materials, a percentage of the money should be transferred to the sellers account which they can cash out using paypal and e-checks. -Also the number of items sold should be clearly available for everyone to see like groupon where you can see the number of copies sold -PLEASE take some time in seeing how the [login to view URL] website operates, you will have to sign in their website to know how their system works. I am also looking for freelance who can give me suggestions of how I can be different from my competitors. -I am looking for a very experienced, creative and imaginative freelancer company who has done a very similar project before which they can show me in their portfolio.
