sounds like you were reasonable and upfront about the cost. VERY reasonable. I live in a small community and love my longarm gal, she is fair with her pricing, sounds like the quilt you did was more custom- I wonder why her sister didn't do it???? I also get charged for the thread used...still fair. I know better than to take a quilt that doesn't have AT LEAST 8" extra on sides and top/bottom. I let the longarm gal choose the pattern- she hasn't disappointed me yet! Draw up a "contract" and go over it with your customer prior to accepting their top.
