We did this for my wife right before the Pandemic. Luckily we already had a 12 foot by 12 foot cement pad in our backyard. The building itself was 10 feet by 12 feet and cost $5000. Then we had to install insulation and drywall which was another $1500. Then I had a single 20 Amp power line installed and that cost another $1000, but I also had him do some other work and I assisted with the digging of the trench. I think we were at around $9000 all in with it. I checked with the company and that model of building we got is around $8000 now, so maybe around 60% more now?

OP put in 60 amp service. I can't imagine why you would need that much, even with the minisplit. My flat is three times the size of his office and has an electric water heater and washing machine and it has 32 amp service.
