Hi ran2far,
Sounds like you have some experience under your belt already. The best place for you to start is perhaps in one of the level 2 courses here: https://www.guitartricks.com/experienced.php
And if you want some advanced theory stuff, look no further than classical: https://www.guitartricks.com/style.php?input=classical
Hope that helps.
