To send out here in NY Hudson River Valley-.02 inch for meander or pantograph. .025 and up for custom work. You provide backing and batting. Some places offer binding or sleeves at addtl charge. My LQS has a brochure of quilters and I've developed relationships with 2. (Same prices but one is better but slower)
I'm doing more simple work myself...but mostly because I'm cheap! The longarm ladies really do beautiful work and it frees me up for more piecework...which is the part I like.
