I will respond tomorrow with a mock contract addendum, for your approval. Then we can go from there.
I believe I would have the solid time to work in 3 images between now and mid-August, especially if we start immediately. I definitely cannot do any unpaid samples, though. I apologize for that.
Also, I am loathe to mention that I am still breaking in this new computer, and all time promises are contingent on it not going to the shop for the 3rd time! (Haha, grrrrr).
