You are going to have to get the General Contractors license. Understand in Minnesoooooota that you can't hire any subs without you being a licensed General.
That means: when you need to hire an electrician to perform rewiring to install a sump pump or you need to hire a licensed hvac to fix the non-functioning furnace you legally can't. Will you get caught? Depends on your luck. There are so many items in MN that we have to pull permits on (and you have to be licensed to pull permits unless you are the homeowner) that you might as well get your licensed...otherwise there are a ton of P&P Contractors in MN (especially the twin cities area) that will be more than happy to report you.... We have been checked by State Licensing Board 4 times this year alone from "anonymous people"...
Whats fun is the people "sanding off" the paint on the basement walls and applying Drylock that are NOW getting the $30k fine letters from the EPA for RRP Violations since AGAIN someone has been turning them in to the EPA. If licensed and the records are OK than no problem.
OH yeah: Can you be licensed EPA Certified and not be a licensed contractor?
