Around here we have everything from simple self care to really extravagant full care places.
Top of the heap within 5 miles of me is this one: Welcome to Four Rivers Sport Horse
Can't even THINK about affording that place, but it sure is beautiful! Not to mention my poor little QH would be the laughing stock of that farm and all it's pretty ponies! (Just kidding, there are some really nice folks out there.)
Full care, and I do mean "full" care is $615 + hay surcharge.
Heck, even pasture with 2x feed is $335! Ouchies, just a dream for me.
I keep Fayde at our county fair grounds for $35 a month, until life quits throwing monkey wrenches at us and I finally get a chance to get my fences up and bring her home. That includes a stall, tack room, hot and cold wash racks, paddocks to turn out in while you are on the property, access to a round pen, small covered (but actually outside) arena and large outdoor show pen. Oh yeah, and a 1/2 mile trotter track!
They don't supply shavings or straw for bedding, gotta supply your own, hay, feed and supplements, too. No one feeds or waters except the owners, three trips a day to the barn with this nasty hot weather hasn't been much fun, but you do what you gotta do.
