I've taught my son how to deal, he deals my monthly game.
If you are teaching someone how to deal, you first need to work on pitch, proper shuffling, ssbs, then functional aspects of the specific game, then common errors and rulings, then how to calculate the pot, then when to calculate the pot. If you're in the game you can give the play by play for in the moment issues.
I would highly suggest
not using a round table, and picking up a shuffler, they are not hard to install. (you'll want to use poker size cards as the shuffle master boxes cards from time to time)
Tips, I think if your players are tipping chips its a grey area, but a dollar a hand for plo or nlh is decent, if you're playing mixed games an hourly rate would likely be more appealing.
I've met some of your locals and I have to say, whoever you find will need to be able to be aggressive when the guys are all talking over each other and laughing. (Inferring they are average lively bunch when it gets going

)
It shouldn't be hard in Texas to find a dealer, I'm sure there are people who have worked at some of the semi-local card rooms. Find an underground game and start networking there, it won't take long.
