It's been a while since I sent out a quilt for longarming. When I did, I usually chose "computerized", because the price is much lower here (DFW). The price for "custom quilting" is twice the cost of "computerized". I made a special quilt for my late spouse - a Texas quilt. (He was very proud of being a 5th generation Texan.) The cost for Custom quilting was 4 cents per inch, while machine quilting was 2 cents per inch. This was about 7 years ago.
Maybe you need to re-think your point of view. What you do is "custom" quilting, not FMQing. What they do is "machine" quilting, while you do custom quilting. Language is very important when you are selling something. Even if someone says, they prefer "computerized" quilting, you tell them you don't do "machine" quilting. You do "custom" quilting.
