I recently put an ad on Gumtree here it is:

“I am a Graphic Designer willing to do it for free!
This is so I can create an extensive portfolio for potential employers.

I will do anything like magazines, posters, business cards, websites, wordpress blog designs (£50 for own URL) , band bio’s, CD covers, flyers, anything I can get my hands on.

If you are interested email mail@rjrigby.com or check my website www.rjrigby.com.

Why not try it before you go to an over priced design studio.”
