I have no experience with long arming as a business, but I have met several gals who do. They love their Innova's with the computerization. One lady that I saw her setup was 3 of the Innova's. She had all three running when I visited her to pick up a friend's quilt. And had at least 30 or 40 quilts ready to load. She said she could do at least 6 a day if they weren't huge. The cost of the computerization is big, but how much is your time worth? You still have to load and roll the quilts, but it seems to save a large amount of time and the designs are extremely accurate.
