Using you CFI to act as a safety pilot for free for a guy that owns a plane and is licensed already is one thing. Doing actual instruction where there is a much higher risk to yourself for free is just stupid. I'm desperate for flight hours but I'd never do actual instruction for free.
If there is anyone actually considering this, print up some business cards and hang out at your local FBO and talk to people. I've gotten to ride along with a bunch of aircraft owners and gotten some time that way on top of the normal paid instruction I do. Not only do you build a little time but you meet people and network. You never know when or from where that good job will come your way.
