A fellow solo-act and myself team up from time to time on the big jobs, to help each other pull, lift, etc. Since we're both legal contractor's, no hush-hush required.
The carpenter crews I work with have the same deal. They're all contrator solo-outfits who sub each other for help. Keeps the Comp people away!
