Find a local tech or music store that sells tube amps. They should be able to bias it in under an hour.

I use a bias probe between an output tube and the socket. Adjust wall voltage to 120V AC with the variac and set bias current for 34-35mA.
Any tech can handle this, should be a standard bench fee.
