I'm representing a UK patient-led initiative for Lyme disease and I'm currently preparing a fundraising campaign for two scientists to develop a more reliable diagnostic test as the current NHS test is very unreliable and thousands of British people are going undiagnosed and untreated. I'm looking for a graphic designer to help me realise a logo for our fundraising Facebook page. I will also need to be able to print the logo on a white T-shirt. Unfortunately, there is no budget; so I'm ideally looking for a designer that would be willing to work on a donation-basis. Can anyone help?
