I need work very much, and I'd love to earn bitcoins

To get an idea of how many are in the same boat, see how quickly the service called ForBitcoins (referenced by Brad just a couple replies up) has grown in just a few weeks:
  - http://www.forbitcoins.com

There are a few similar services:
  - http://www.bitgigs.com
  - http://bitcoiners.org
- https://workforbitcoin.com
  - http://en.bitcoin.it/wiki/Category:For_Hire

Technology is moving us towards a more collaborative, peer-to-peer economy.

We can rent out a room for the night ( http://www.airbnb.com ) or serve dinner from our homes ( http://www.housefed.com ). We can share with a neighbor ( http://www.neighborgoods.com ) for free or for a fee, and also extend that offer to others as well ( http://www.rentalic.com ).

In addition to the "task related" services described above ( http://www.zaarly.com and http://www.coffeeandpower.com ) here's an example of another novel approach:
  - http://gigwalk.com

Though none of these peer-to-peer services have implemented Bitcoin (yet), that's likely coming:

Is there possibly a Bitcoin meetup or hackerspace in your area? A connection made there might lead to an opportunity you might not already be aware of:
