onepaw: If you have Skype (it's free), I'd be happy to help out any time. I am usually sitting near the computer with my fiddle next to me or in my hands anyway. Feel free to PM me and we could set something up.
The tuner is a good starter, but you'll go through batteries pretty quick. If you can distinguish correct harmony notes using a drone works pretty well to find correct intonation. It is also great ear training, which you'll need in the future, as the tuner won't keep up with playing a song up to speed.
