I have a rotating composter in my unheated garage that stays at between 70 and 80 degrees. How long will it take to have finished compost at this rate?

There is no easy way to answer that. It really depends on many things, such as what you are composting and how often you turn it and how damp you keep it. But with small, closed composters like that, you can expect compost in 4-6 weeks under best conditions.
