I would look around - mostly ask around - a little more. There may be more options close ish by that you're not aware of. And - it sounds like you work outside the home. I don't know what your work schedule is or how populated the environs of your work are, but maybe there's a daycare on the way ish?
For me, who was used to finding just about everything via Google, the daycare market was obnoxiously offline. Very few in-home daycares are on say google maps, and no nannies. Even daycare centers often have subpar web presences. The only central listing of daycare centers and in-home daycares that I found was a state website. (Which was just a giant list of everything in the county, so filtering to close-by providers had to be done manually.)
Anyway, all of this is to say, ask your friends and neighbors if there's anything else.
As a last resort, if your home location and jobs are non-negotiable and there are zero other options, I would personally probably accept the daycare you found over unnecessarily driving 2-4 hours every day to somewhere better. Parental time and energy is in short supply, and my calculation would be that the likely outcomes of layering a huge commute onto two working parents (fights, exhaustion, somewhat increased risk of divorce...) are probably worse than the likely outcomes of what seems to be a subpar daycare. (Who knows, maybe the owner was having a bad hour and isn't actually burned out? I would still be concerned with a non-burned-out owner, somewhat about the kid ratio but also about the availability of backup staff in case of illness/whatever, but less concerned?) But I would investigate all the other options first.
