I only know Frank, I dont know Mike Wolf at all.
No they are not working for free, I have no clue what they are making
Mike Wolf is actually the guy that started it all, he had videos of him pickin on youtube and has been trying to get the show picked up on a few networks, finally it did and he brought his buddy Frank with him, who is also a picker, they have been friends since grade school.
I wish they would show some of Franks stuff on a episode, you would not believe the amount of stuff this guy has for motorcycles and his knowledge of them,
