A friend has asked me to design seven posters for forthcoming events at the charity she works for. Some will be pretty simple and bold, some more complex and artistic. They are supplying all images and content.
They have suggested paying me £10 per poster - asked if it seems reasonable - and, if it doesn't, to name my price. Each poster will take between maybe half-an-hour absolute minimum and a couple of hours to complete. I think £10 per poster is peanuts! (I know it's a charity, but I already do this for free for a couple of other charities and am looking for work.) But, having never done this before (in a freelance capacity, or as my full job in an employed role), am not sure exactly what to charge. Any ideas? Thanks.
