If not for charity there's also the possibility of doing something cheap for portfolio fodder. Then again, cheap seems to bring out the wrong type of person you want to work for.

You could also subcontract for someone you know that does web development. They get less work to do, you get experience, you probably still get paid.

I find its better to not work for cheap, either charge full price or work for free, demonstrate your value or donate time, dont undervalue yourself.
