I don't know where abouts you are but if you have a small traditional wool or haberdashery shop anywhere near you that's a great place to try.
I am not a brilliant knitter but do have a go, and the last time I was in a charity shop buying wool and old fairisle patterns, and chatting to the retired lady that was volunteering in there I had to almost forcibly stop her from taking me home thereand then and knitting me an entire wardrobe!
I do get the impression that good knitters simply love to knit, so if you can find one that's not busy making things for their relatives then I bet they would be happy to help!
