you better try FOREX .. trade on your own , be your own boss and from a comfort of your time .. we are controlling our self and we only can lost our money if we make a wrong trading
this is a good idea but forex needs professionals & at least the should have he basics so it isn't easy to start investing in forex if he is newbie.
I think the only good site that I know and can tell you is TroyBank. It is in the field of HYIP for the last 5 years or more. It is Paying Everybody. But all programs are long term. 100 days or more. You can check information about this from other forums also.
The best way to invest that is in different programs, if you are just starting with online business then I suggest try with $1 - $5 investments first then if you are familiar with the system how it works then it's up for you to decide.
