Maybe check phone books and stuff for music stores... if they don't give lessons they probably know where you can go.
The chance that a guitar teacher in your city in texas will be on right now to read your post and email you are very, very slim. So you might as well check the phonebook or newspaper ads.
edit: ^^^ yeah he said that too, and also go to a guitar shop!!! i got my guitar teacher recoommended from guitar center.
