Hello Carolann
Sorry to reply late.
You just pay price for pictures post send to you, as bills from Post office.
Don't serious, i am welcome to help, because my home, my office is nearly post office. I post post office and Grand Market (the man painting) everyday.
So for fair, I charge labor costs (manage) 50 The piece.
Then you pay the price of the painting by Bill and receipt from post office. No more charge from me.
I hope you will understand my English...
Best regards
Pen
