We ought to talk price right up front. If I'm going to do this in two weeks I'm going to have to take a lot of time off of the job that's paying the bills. This is a job for me. Some patrons think that art shouldn't cost much because it doesn't have a concrete function in their minds, but if I put in a hundred hours to paint this, I am going to price it like a hundred hours of work.
I can do an 60x45cm portrait for 520 Galleons. If you think this is fair for a delivery by the 13th, I'll get right to work.
