What are the wants/needs of the OP for the future barn they wish to board at?
In Ca, generally speaking, and this is my observation, if you don't mind doing a lot of the work your barn's manager and stall hand should
be doing along with a few other tasks, for instance, my "barn family" created a private facebook page to update each other on feeding, how much water each horse has and shavings in stalls so we don't have to constantly stress over weather or not my horse was fed or not etc... all at the cost of a relatively lower boarding fee in the Bay Area.
So basically, $200 - $400 you can expect to do a lot of the maintenance yourself
$500 - shoot-me-now price range you can expect much better service and are farm more likely to have property owners
who actually know something about horses . . .
