This has become an even bigger mess. I ended up contacting Resdoor in Fort Worth, which seems to a be a reputable local door supplier. They only sell doors, no installation, so they referred me to a local contractor.
I called the contractor who came out and took measurements, then gave me a quote for $10k that I thought was fair. I agreed to pay him $5k up front, he ordered the doors, and then I would pay the remaining $5k once the work was finished.
The doors got delivered to my house and he came out to do the install, then he said he couldn't because the doors were the wrong size. He said he gave Resdoor the correct measurements and he suggested the mistake was on their end. I felt like that should be a simple fix and that he could straighten it out with Resdoor and get the doors reordered correctly.
I got busy for a couple weeks, then the holidays, then I hadn't heard anything from him so I checked back in. He kept saying he needed to come to my house to do something, which I assumed was to repeat the measurements. It took a couple more weeks to arrange a meeting date. When he showed up he wanted to see the doors and take pictures of them, which he said was because he now needs to sell the doors on Facebook marketplace. What the fuck.
He said Resdoor won't accept a return or replace the doors which obviously indicates the mistake was on his end and not theirs, even though he won't admit that to me directly. He also says "his company" doesn't have the money to reorder doors until these doors are sold. I have no faith in him selling custom sized doors on Facebook. I have no experience on Facebook, but using my wife's account and searching the marketplace, I can't even find the doors listed on there and it's been ~2 weeks.
I called Resdoor to get their version of the situation but the salesperson who sold him the doors is now on leave until March. Just my luck. They are looking into the situation for me, but it doesn't sound promising.
I've tried to play nice with the contractor to give this a chance to be resolved amicably (ideally that would mean the work eventually gets done correctly for the original agreed upon price). We're at the point where I need him to either pay for new doors out of his own personal finances or refund my money. I think the likelihood of either happening is less than 50%, which I guess that leaves me with the option of trying to sue him to get a refund, which sounds like a huge pain in the ass and hardly worth the time.
