This thread will probably be deleted, but before it is, I'd like to tell you that you have bigger hurdles to overcome than the technical aspects of running a hidden service. SR competitors are unlikely to succeed for the same reason that Facebook competitors are unlikely to succeed. Facebook benefits from the network effect: everyone wants to be where everyone is. Buyers want to shop at the marketplace that has the most vendors (and product selection), while vendors want to sell in the marketplace with the most buyers. It works so well that SR can charge $500 for a vendor account and still get more new vendors than BMR or Snuj. BTW, take a look at the Snuj market. Started a couple of months ago, it appears to have gone nowhere, even though the site design and all that decent.
