I have a contorted quince. It flowers quite a bit and is a cool looking tree. Just make sure to cut the flowers off as soon as they are spent so it doesnt put energy into fruit (unless thats what you want) I found a cool reference sheet for them online let me see if I can find it.
Welcome from a fellow Wa (Yakima) BNut! If you put your location in your profile, it will help others give you more specific advice.
I started my first quince this year and it seems to be very good material to learn on (e.g very tolerant of mistakes and too much "love").
Welcome to the site. There are lots of great places for beginners to read about bonsai, and the Reddit wiki is probably one of the better ones. I’d recommend that you read the stuff here, especially the beginner’s walkthrough:
If you have more questions after reading that, and you probably will, feel free to ask.
I’ll give one pro tip: First, focus on keeping your trees alive and healthy. Then after you have that down, then you can focus on “bonsai techniques” like wiring, repotting, chopping, defoliation, etc.
I hope that you find bonsai as enjoyable as we do.
