Budget for one or two months in Kazakhstan ?

Hi! I'm planning to visit Kazakhstan in September 2027 when I finish university. I want to stay the longest time possible, but I don't really know if it is realistic considering my budget. I would be able to save around 4000$. Is it possible to stay there for one or two months? I live in Canada, so the flight won't be cheap (about 1k$ right now just to go there - maybe it will be more affordable in the future?). I don't care about being comfortable, and I'm used to traveling cheaply. Is it realistic?
