Qwerty - I just want to offer you an alternative "vision" perhaps. Zugor's mention of the powers that be made me think to add it here.
I live in a large, sparsely populated very rural, 100 + 10% ranching county. The biggest town, the county seat, has a population of approx 7000. Well, so they say, I'm still trying to figure out were 6500 of them are hiding.
I don't know the background - i.e. the how it all came to be - as we're new out here, but it is what I'd call a public-private partnership. The county or the town provided the building - not a purpose-built, no, but some disused building they owned in town. I don't know who did what exactly but I know that with the county's weight and clout behind them, they wrangled some deal with the local distributor of a national pet food. They wrangled some deal with one of the local vets for routine vax, spays & neuters, etc. I say "they" but I suspect most of it came down to one older woman who just does not take no for an answer.
I don't know all the political shennanigans that went on to establish the shelters, but I can image they were not few in number and it probably takes immense will-power not to end up throttling someone. But, at the end of the day, the shelters are there and serve the animals well.
At the cat shelter, volunteers do all the care-giving, cleaning, admin, ferrying to vets, being there for opening hours, etc. It comes down to a core of very dedicated individuals. I don't have the same working knowledge of the dog shelter (it's in a totally different location, well out of town), but as it goes under the same name, I suspect it functions more or less the same. The cat shelter is a no-kill; I cannot say with certainty for the dog shelter, but I think it is too.
The smartest thing the group of mad cat women (as I affectionately call them) did - given the where - was to form an alliance with a different feline rescue about 100 miles away in the closest city. It tripled the rehoming rate. Out here, quite literally, there are not enough people to sustain rehoming of the steady stream of homeless cats. I know the dog shelter is involved with sending some of their dogs to a women's prison in a neighbouring county for training to make them more adoptable.
Perhaps something along the lines of this type of arrangement is something to consider too.
