Welcome vario and crabman.
Reading everything you can is good. Learn about your soils, watering, fertilizers, and the environment each of your trees need to survive. Bonsai Iligan has lots of nice videos. I like that he uses many plants, pots, and soils that are available to him locally.
Personal suggestions to add:
*Look for locally owned nurseries if there are any. Some of them have far different trees and shrubs than big box places. They can have better prices too. Remember it's ok to not buy anything too
*Try taking some cuttings from local trees and bushes. Something to take up a little more of your time. It's fun to try. I have some boxwood cuttings from my first year of Bonsai that almost look like bre-bonsai now.
* Find a club and if there is a Bonsai convention within driving distance go. Nothing makes you want to dive in deeper than seeing nice trees on display.
Don't get discouraged! You can do as little or as much work as you want in Bonsai. Just keep at it. And try not to kill all your trees at once
