I have been working out an event with World Concern based in Kent. They are a non-profit that help refugees. We have already begun the discussion, but I don't know how many people to expect yet and so I don't know how many photogs and support needed yet. If you are interested, send me a message and I will keep you up to date when I hear anything.
I'm in Kent and would be more than happy to help!
I would be interested in helping out with the Kent event. I have lights but no backdrop. I have in the past just taped a seamless to a wall. I would be willing to do whatever is needed. You could email me at ron dot heusser at gmail.
I would be very interested in helping out. Please keep me posted about the event.
