Check your local quilt shops, quilting buddies, quilt guilds. Someone is sure to have some favorites. Some LA charge by thread usage, some by size of the quilt, by the square inch. Then if you want 'custom' that can be another expense. It does add up. My local LA is very reasonable, but another in the area for the same quilt would be almost double what mine charges. So you do have to 'shop' around.
Also another thing to consider is the turn around time. For example if I am making a 'Christmas' quilt, it would have to be to my gal in Sept/Oct. So make sure and ask lots of questions.
I also know that some where in your area there is a shop that rents longarms. A gal on another board did this, I think she was in the southern part of Seattle area. You have to take a class first, but then you would be able to do them yourself, for a fee (of course), nothing is free.
Good luck on your search!
