Okay, what you need to do is join an affiliate network. What you do is place banners on your site and every time a user clicks the banner and registers/sign ups you get $$$. I only have about 1500 views / month on my site but I making about $150US a month (so you should be making around $2000/month!). What is you niche? Drop me a PM if you want some good affiliate networks. Cheers
"I have 30k visitors but not making any $$" it's unreal, and what about your site? May be you don't have advertisment on it?
