I'm a licensed engineer, including PA and have engineered hundreds of log structures from giant sign towers, to $18million + lodges, to tiny cabins. Log anything is not anymore labor intensive than any other wood structure. I live in a log house so that's coming from personal and professional experience. If you are willing to do a crawl space foundation, you're more than half way there to code compliance. The rest is electrical, plumbing, egress windows and doors, and roof insulation. Conestoga Log Cabins (PA based) has a lot of options and the "logs" are precut on a CNC machine. Super exact. Their logs are actually glu-lam beams shaped like logs so much stronger and no settling issues. If you want more traditional logs, I have contacts for those as well. Feel free to PM or message me.
