Cheapest way to board puppy?

I don't see why if she has food and water and a place to use the bathroom that this is abuse but may i suggest if you have a regular vet a lot of clinics offer day boarding at a relatively good price that way at least someone can be with her all day. If this is not an option i don't see why this is any different than crating your pet all day in fact at least she will have some room to play, if you don't mind cleaning up the mess when you get home. I would make sure to leave lots of toys for her to play with.
