50-100 is a pretty large range. I did a quick spin around the job websites and the estimator (demolition some interior demolition) compensation averaged between $90 and $140k. Some of them only required 2 years experience.

The state is looking for an estimator with interior demolition experience to prepare estimates for future agency budgets. It pays $83k + a pension. You have to have 5 years experience for that one. It's 40 hrs per week, all paid holidays, 3 weeks vacation the first year.

All I know is most years my profit sharing exceeds my salary, which is a good setup to get.
