Getting power to the new shop

Have you considered the possibility of upgrading your house panel to 200-300 Amps and running customer owner wire overhead or undergound w/duct to your shop?
Then your shop will be a sub panel.

Is you house service overhead or Undergound?

Another idea...If overhead, ask your power company if you can have two meter panels with two weatherheads next to each other. Then power company upgrades the OH service feed to handle combine load of both panels. You would just run a jumper from one weather head to the other. Then your garage panel/meter would have to OH or UG feed a garage sub-panel like in the first scenario I proposed.

The power company's and state public utilities commission have varying rules about how many meters per address or dwelling unit (cooking facilities), where meter can be, length of OH service wire, and maximum "dirty power" (voltage drop & flicker) for new service. Etc etc
