I run a bitcoin exchange site which also has a "sell your coins" section to it, sort of like if arumexchange & fastcash4bitcoins got together & had a baby...that'd be my site.

Anyways, back on topic, I've meant to start a bitcoin laundromat service for over a year now..The reason why? Since  (for the most part)  money laundering is pretty damn illegal, most business owner/launderers wouldn't be running their services on a standard tld (.com domain)

They would be running it on an underground network such as TOR. Yes, I could have simply added a laundromat part to my site years ago within 10 minutes, but I didn't and the reason I still have not is because like I said, I don't want that kind of heat or attention out in the public eye.

I'll have to wait til I setup the .onion site I created.

Bottom Line to my long as post: Try searching the tor network of sites. There are a couple searchable directories. I think there is even a bitcoin or tor wiki with a list of bitcoins services.

I can recommend some if you want too.

Hope this helps at least a little!
