I have personally done a lot of clearing for myself. Did another 5 acres this past summer at our place in CO. I am not sure how the professionals do it, but for me a big excavator is a necessity. You could probably save yourself a lot of money by doing that part yourself. Biggest problem is figuring out what to do with all the material you're gonna generate.
EDIT: I should clarify it depends a lot on what needs to be cleared. We are taking down HUGE mature spruce and fir trees. Lots of the over 100'. If it is all small stuff I am sure a dozer would do just fine.
