One way to get a lead on who can install meter pole is to contact your local electric provider. I think National grid operates in Canajoharie. Call and ask to speak to a field planner. These people, as I was one before I retired, will know the scoop on who can install your meter pole, install pole anchoring, and wire it too.
First 100 feet of overhead service on private property at no cost to you, anything over 100 feet is chargeable on a per/foot basis.
If you just have a travel trailer, expect to pay for all footage until a permanent structure is built, then you get a refund.
Good luck.
