You can try programs like Paid To Click (PTC). I am earning 200$ - 300$ every month without spend any money. You can work on your convenient time from your computer. they pay you money for visiting their websites. (for seeing their advertisements). they pay you money through Pay-pal, Alert-pay or check. All you have to do is to register on those sites for free and start earning money by surfing ads. I have found a site

which has a collection of paying websites.
