Poster for Charity Prize Draw

Hi there. We don't have a budget for this but one of the trustees is willing to pay £20 from his own pocket to have a poster designed for a Grand Prize Draw we are holding. This is needed ASAP!
If you are sending examples of work, please ensure they are posters and not anything else, so we can get a good idea of what you can do for us.
I appreciate this isn't going to help your retirement fund much, but you will be doing something very worthwhile for a wonderful charity (www.theliferightfoundation.org) which helps abused and neglected children.
Thank you and look forward to hearing from you with some examples
