That’s not new wiring, FYI. Some may be new. Perhaps they brought the bathrooms up to NEC 2017 compliance with dedicated 20 amp GFIC outlets, but I see old wiring too.
We can’t see the top of the panel, and my guess is there’s more wiring coming into the panel there.
Any electrician can handle what you want. Just ask them to quote a window box AC circuit and (2) 20 amp computer workstation circuits. You’ll be fine with that. Tell them you have two discrete workstations, both running 800w power supplies, and numerous peripherals, if they care.
