I'm too cheap (poor!) to pay someone to quilt for me - I do all my quilts on a Brother innovis 1200. The more I quilt, the easier it gets. Practice makes perfect (perfect enough for me that is!) You just have to do it enough that it feels 'comfortable'. Find a design that you can deal with (meandering, waves, whatever) & practice practice practice. It doesn't have to be perfect; small mistakes get lost & are not noticeable. And fabric choice (like for your backing) is something to think about too - a busy fabric will hide a lot...invisible thread helps too.
