Private driving lessons in Houston

Hi,

I've been living in Houston for several months now and have no choice but to get a license and get a car. I am about to get a driving learner permit, but the problem is that i finish work around 7 pm everyday, i've heard from taxi driver that there are some instructors who privately teach you full course of driving for around 400-500 dollars. Is there any recommended contacting info you may know? thank you in advance.
