Hey man, nothing to apologize for. We’re all friendly here.
The only person I’ve seen recommended is Verno at TheHolyMackarel, but I’m not sure they’re still around and never had any work done by him. Since implants are technically considered illegal in Hennepin county, I’d try body modification places out in Saint Paul or Roseville. @amal wrote up this guide on approaching shops. Per my recollection, the XG3 installs similarly to an x-series RFID chip, albeit likely in slightly different locations. @backpackingvet might also be able to help.
I’m also happy to meet up to talk RFID down the line if you ever want it.
