Wow! Those prices are too low to sustain a business! When I got my Millie, I thought I would start pricing at $0.15/sq inch. I was shocked to discover that the local quilt shop did a meander for $0.10. That price includes very basic type thread, and does not include batting.
It is very easy to keep busy if your prices are too low...You have lots of work, but no time and not much income.
It is very true that you get what you pay for....
