Machine Quilting

I have been ringing around to find out how much it would cost to quilt my Japanese Kimono Fabric Quilt because I thought it might work better than the usual hand quilting I do. I've also been reading stacks of blogs and have found that lots of people just seem to manage doing the machine quilting with their ordinary home machines. I really can't decide what to do. I know $150 - $200 is reasonable because of the work involved but should I try to do it myself and risk the mess? I have a walking foot - I am just scared.
