We are also on a large sloped hill with 50 feet of frontage. We currently have an existing bunker style garage/shed from the early 50's that goes into the hill about 20 feet. Our lawn sits on top of the garage.
We considered and got quoted a number of options and the cheapest 2 car garage we were able to find was $170K. The excavation work and retaining wall work was very complex. Spitballing and without knowing I would say you are in for far more than $45K.
For reference the grade from the street to the back of the bunker probably would be a difference of 14 - 18 feet so we are talking a pretty serious slope.
