Looking for reliable contractors in Southern Oregon

I'm looking for reliable contractors to install structures with plumbing, electrical, hvac, etc into the side of a mountain in Southern Oregon. The property has constantly flowing water, so I'm also looking for someone who can source and install a small hydroelectric generator. Lastly, the access road had already been installed, but I'm looking for a road/trail crew to expand and improve access throughout the property. I'm hoping to start work in May, before fire bans take effect. Work will recommence once fire bans are lifted and continue until November. Any leads would be greatly appreciated. Thanks!
