Regarding unpaid overtime compensation for done

Mr. Meltonburger,
Sir I am contacting you for your advice. I worked for Choice Hotels here in San Antonio as a maintenance man for two years. I work 6 days a week 10 to 12 hours a day sometimes 9 but I was never compensated for any of my overtime. I was given a room that cost $350 a week which they said came out of my check and $100 a week an actual direct deposit but never was compensated for my overtime. I was also terminated my wrongful termination which can be proven in court but I understand that in Texas they have that no wrongful termination law. The reason that I really need advice on is that do I have a chance of winning money back from my employer. I would be willing to give you any information that you need to look into my case it was two years of work and a lot of overtime and I didn't fall under any maintenance extra Duty time or anything like that this was straight-time work through the day before I got off and then sometimes they call me I'm not including those hours I'm including just the base hours of the day. Sir if you could contact me please with any helping my situation I would appreciate it I'd like to obtain your assistance if possible thank you for your time.
