Tom, I'm in western Nevada. Not sure of the nearest
city and your budget, but you can rent a truck, trailer, and skidsteer from Reno for ~$2K for about a week which is probably way more than you need. I'll dig small holes with hand tools but anything resembling real work (trenching, grading, road building, etc) I'll call in the little-big-guns like a skidsteer or mini excavator. If you have any friends in construction they very well might own one. I paid a friend for gas, bought food for the weekend, and gave him $100/day. He brought a skidsteer out and did some work, showed me how to use it, watched me from a
lawn chair while he drank a beer and yelled instructions at me, etc.
