It all depends on size and difficulty. I usually paint on a 16x20 canvas. My base price is $125 and it goes up from there depending on difficulty. The base price for a 24x30 canvas is $200.
I do custom orders, just specify by commenting or emailing me exactly what you'd like.
I have shipped so many paintings, at least 50, and have yet to have a problem. The paintings arrive safe and in perfect shape.
If there does happen to be a problem, I will be more than glad to discuss solving it with you.
