What site is the best to make money?

I don't know if you make money online without any investment. I suggest you to look for a jobs on odesk or freelance because you can earn such amount if you accept a job from those sites

It's going to be tough unless you have a niche skill. Writing is a good suggestion but will take alot of dedication. Earning that much will be hard. If it's smaller amounts then there are various sites that could help. I have a blog on the subject if you're interested in finding out about other ways of earning. I believe it's listed under my profile. Good luck.

Are you serious? Well a home based business would probably help you out there. I mean there is really nothing like that where you can do that unless you work really hard, but I mean if you think that you can work hard here then yeah set your earnings to like 100. Are you are good writer? If so you can try freelance writing and writing for clients to see what you can earn, so I recommend Odesk if anything. Like a writing site where you can write and earn money. Good Luck
