Here are yet ways to earn money on your spare time: 1) join focus groups. These usually take from 2 to 3 hours and you would normally be paid in cash. Here’s a site that has a listing of advertised focus groups where you can search by city or state – http://findfocusgroups.com/.
2) Join www.daytipper.com where you can submit a tip and be paid $3 if it gets published. (A good site to pick-up tips for yourself too!).
3) Be a search engine “human” guide at www.chacha.com/info/guidesignup where Guides earn between $5-10 per search hour based on performance. The only drawback: you have to be recommended by an existing guide 😦
