I don't know about formal training. I know there are trainers out there, of course, but I couldn't tell you which ones are good. And that's pretty expensive, anyway; reading manuals is more my style.

I don't mind explaining things in VBA—I kind of like it, actually—but if you're looking for a more organized approach, there are probably textbooks you can find on the web cheap or free. Afraid I'm not much help, am I? But go ahead and ask me something, and at least I can help explain certain topics ("What's a collection?" "How can I read a text file?"), or help you work your way through a particular problem.
