What would be a nice ranch to stay in the state of Montana for single 30 year old females?

I would like to stay at a ranch for a few days and not the full week as most of them are requiring. They all appear to be pretty expensive too and I don't want to spend too much.Any names of ranches would be great that fit this criteria. I have never been to Montana and I am wondering if I should skip the ranch and do that another time. Instead I could just check out a rodeo and see Yellowstone or Glacier National Park. I want to have a nice girls' 4-5 days time together in Montana. Any thoughts are appreciated about what to do in the great state of Montana would be great.
