I don't know what to make out from the conversations posted above. OP's website certainly doesn't look like he's not serious about business. There are a number of items listed for auction and most of them seem legit. The VIP membership part bothers me. OP, why can't you send 0.02 BTC for the interested members and they sign-up as a VIP member on your site?
What about his site looks legit? where does it look professional all he did was get a free leached ebay source code and put it together for free.
The items are not legit at all do some google search, reverse image search them to find their true source.

If he was serious he would of at least hired a front end designer to make the website look nicer and more user friendly.
