Micro charity looking for photographer in London

Question

Hi, I'm new here. We are a micro charity and support young tongue cancer patients. We are having a meet up in London on Sat 14th December 2-4pm and looking for someone who would be up for helping out a tiny charity by capturing it. I am myself a tongue cancer survivor and we are in the first year of being a registered charity. So your contribution would have a bit impact as we'd be most likely use the images on our website and social media going forward. The best I can offer is to buy you a few drinksn, cover your tube fair, give social media shout outs and a testimonial. I'd love to offer more, but I just can't at the moment. Also very happy to welcome any students or freelancer just starting out.
