Hi i'm a graphics student and i did some graphics as a favour for a friend of mine. they really liked the work and i'm now being paid to produce graphics for the charity that they're involved in. (they're paying me £9/hour) but now someone who helps out the charity who also runs another small business wants me to help them out by doing graphics for them. what would be a good hourly rate to charge? (as a student designer...) does £9/hour sound like a good rate to tell everyone? or should it be different as it's for a business? thanks... any help from people in the know would be much appreciated.
