As far as no no's etc., they vary from state to state, and from county to county, city to city. I suggest you check with the local county court office to see what permits are needed in certain cities or counties, and check with the state of Texas as to what they require as far as permits and taxes. Maybe someone on the group from Texas can help with specific questions?
Here in MD, they have a multi part tariff structure. You may have to buy an operator's license depending on what county you operate in. In Baltimore County and City, it is $200 per year for the op license. In Anne Arundel County, it is $2000 (yes, thousand). Then, you have to buy licenses for each individual game. In Baltimore County and city, that license is $230 per machine. In Anne Arundel, $100 per machine. Some counties like PG COunty and Harford have no license at all.
Then, you have to pay the state a percentage of your income, depending on what jurisdiction you operate. In Baltimore Co/city, the rate is 10%. In Howard County, the rate is 7.5%. Prince Georges County is 5%, etc. You pay this tax every month to the state, and they distribute the tax to the different jurisdictions. A couple of counties and towns don't have this tax, but not many.
Vending machine or bulk machine licenses will probably differ from the amusement machine licenses in that they will be much cheaper. While you're at it, you should look into a good insurance policy. I had a friend who had a pinball out on location, and some kid simply walked up to it and pulled back the ball plunger. He put the webbing between his thumb and index finger between the cabinet and the plunger, and when he released the plunger, it ripped some of the skin there off of his hand. Had to be rushed to the ER, and it cost my friend a couple thousand to settle. Also heard a story about a guy who broke his wrist on the trackball of a Golden Tee machine. Be prepared for dumb shit like this, and get insurance.
IT IS A PAIN IN THE ASS... but it's a living.
