Bitcoin isn't a money making scheme. If you want to make money you can either:
- Offer a good that somebody values and is willing to pay you more than you paid for it
- Offer a service that somebody values that you can provide cheaper than you can charge for it
- Gamble. Or "speculate" as it's commonly called round these parts.
The easiest way at the moment is to earn dollars and buy bitcoins with the dollars you've earned. You can offer to work for the equivalent in bitcoins (which will additionally help the bitcoin project) as an option for your customers and then you can save yourself the dollar transfer fees.
