Any recommendations for TNR programs and live trap rentals?

I recently moved to SW Houston and have found myself feeding a small colony of community cats (9ish currently but the number keeps rising now that there's food out lol). None of them have ear tips and the males are um. definitely intact. I would like to work on getting them all fixed (would love to have them up to date on shots if possible too), but am having trouble finding live trap rentals and somewhere that will do low cost spay and neuter without an appointment (because obviously I can't predict when I'll catch one of them). Have not received a response from Houston Cares Rescue and the BARC website has said "more info coming soon" in the TNR section for a while. Has anyone had experience working with a TNR group and know how I can get started? TIA! 💗🐱
