website designer csgo site

Hello i want someone to make me a site like csgoskins.net but just with the spin-king feature. The people would deposit their csgo skins from their steam account onto the site and would be converted into credits. They would be able to win more credits and free spins from the spin wheel(of-course it would be in favor of the site making money) They would be able to use their credits to buy skins that would have been deposited by other people. then they would be able to withdraw their skins back to their steam account. I would also want a feature where they would be able to buy credits with paypal. i want all the prices very low like 5cents a spin.

Does anyone know how to do all of this, the site wont require amazing graphics or anything. I am willing to pay $250 for this. i would want the site done in 10 days or less. i would pay $20 a day and see the progress of how the site is going and how ever much else i owe you when the site is complete. e.g $50 if it takes you 10 days to complete the site
e.g $90 if the site takes you 8 days. so $250 no matter how long it takes you.
