I don't know if this would work in Texas, but we had a monster (100 feet or so) tree go down on our driveway late last year. It took out our power. While the road was blocked so the fire department could wait till PG&E could say it's not a danger, 4 different people came up and asked if they could have it for firewood.
One knew a tree guy and brought him and his crew to hack it up. Another was a landscaper. So maybe a post on craigslist or a couple calls might get you free removal. If you paid someone it would probably be a lot.
If you and your buddies practice smart judgement and build some scaffolding it could be done. I myself would give it a good shot or see if I could get a gone for free before I paid.
