I'll have to disappoint you,..sweet cherries are not hardy for our area, you might get some cherries the odd years but trees are prone to freeze back.
If your'e willing like me and experiment, I find, growing branches close to the ground and hope for snow cover, chances are higher to get fruit. A garden center here has them regular, you might check in your area. I would plant the tree on a angle so branches are closer to the ground, and or weigh them down. Bury the graft union about 6 inches deep, [above graft].
