Jay Friesen runs a good outfit and they can set you up pretty fast. Plus the material will be seasoned and you won't have to strip your land for building material.
If you did cut your own logs , you would have to wait a year or two for them to season correctly while you turned them every couple of months. Having cut , peeled, and turned logs for the family while growing up, I can tell you the the romance goes out of it after the first couple of days.
If you are at the "need a book stage", then you will spend WAY too much time and money.
Just setting up the foundation pilings or piers can be a big pain in the butt.
I have lived in log structures and framed structures during the winter. Framed is MUCH warmer. And lighter on the pilings. There is a reason the pioneers dreamed of a framed house...
Thats way my guest cabin in rough cut timbers and lap board. 6 inches of insulation everywhere...
