As a beginner I can't offer services but in some ways that a very interesting idea that could well be viable. The issue I see is, apart from a willing tutor, the ability to set up multiple images (instructor, 'scope?, flex zoom, +?). An idea/ thread worth following given that there are videos and downloadable tutorials already it might work as a fall back. The key problem is the lack if in person hands on feedback which is extremely helpful when first starting (obviously ).
Tira Mitchell thru her site Precision Artistry has online classes. I have done 2 bulino classes with Chris they are affordable and have useful info. The class is set up so you can ask questions as you go.
Good luck,Leland
