Hi, I am using tor and bitcoins more than 2 years.
it would cost you 100 USD just to configure server for website + you should rent server at hosting that accepts tor. many hosting refuse it.
what kind of website you want to open/make behind tor network?
general specifications of such site should be:
minimal javascript, perfect would be totally without javascript. many people who use tor browser bundle disable javascript for security reason.
simple design without many photos because of faster loading. tor network is network of proxies and it is slow, if website has a lot of images, loading of site will be very slow.
many people created website for selling products behind tor network and they were hacked. sometimes hacked in just one week. typical shopping carts will not work good behind tor, it has also a lot of javascript and many people will refuse to use it.
and so on... and so on. tell me what kind of website you want?
my bid 100 USD is for configuring server, not for making website. I must know first what kind of website you want to make.
