Adult Marketplace

I am looking for someone who would be able to create a adult marketplace website like this one here - [login to view URL] this website would allow sellers to create listings for example fetish videos/pictures and sell them. Buyers would be able to buy credits and use them to buy videos, pictures and merchandise. Sellers would have to pay fees for selling. I need someone who understands how a site like this will work I need something that will make me money and the sellers money at the same time. I would like the website to have a inviting look something sexy and it needs to have advertising spots. I like the idea Facebook has also allowing people to create a ad for a cost which would place them in the side bar, users could manage the ads and add a picture to it. It does not need to be as advanced as Facebook ads just something simple that is automated. The payment choice I like for the site is Paypal it works well for sites like Fiverr. I would like members to have profiles showing their listings, about themselves and pictures. I would need to site to be tested to make sure any bugs are fixed. If I find the right coder I will stick to them and will use again if needed which I sure will if this project does well. I would like the person who is interested to show me some of their work. I am looking for just a quote really because I have no idea what a job like this will cost.
