The Stitch N Frame shop in Bovina, (just before Vicksburg on I-20) rents out time on their longarms. You have to take a one-time class first, which was around $100 last time I checked, but you can get a quilt quilted in that class. I've meant to do this one day, but I seem to be doing fine with FMQ on my Juki.
