I am only 18 months in. Your options for HEB and NFW are going to be somewhat limited if you take reviews and safety seriously.

Patience will be key.

There are lots and lots of things to consider.
-wherever you do your research, make sure they are well reviewed (here or Eccie)
-early on focus less on your ideal provider and stick with finding a 2-3 that are newbie friendly
-don’t give anyone your real world info and use a new/seperate email. Use a burner phone or phone app.
-most providers are late for appointments, plan for it. If they are late or cancel, don’t rush to find anyone who will take an appointment. That when you will run into issues.
-untraceable $$$ will cause you to answer less questions.
-use protection
-be respectful, it goes a long way

This is just a few starting pointers.

Feel free to PM with any questions. I sign in every few days.
