I built http://artistsnclients.com - It was an idea I had back in 2011 but couldn't find time to do. Now I built it, but it doesn't seem to be viable. I had a few people test it and the profit is at about $4 right now. At least I improved my skills a lot thanks to it, especially in regards to financial processing.
Get rid of the warning "use at your own risk". That's what the Terms of Service is for, on every site.
I'm quite surprised I got any upvotes.
