In-wall insulation

Does anyone have a recommendation for a Duluth contractor to add insulation inside walls? I had an energy audit and the auditor recommended adding insulation inside my exterior walls, since there’s no insulation in there right now.

This is the first large project I’ve undertaken in my house and I’m intimidated by the process of picking a contractor. Before anyone suggests it, I did go to an informational class through the Duluth Energy Efficiency Program and submitted my information, but my house is already too efficient for me to have access to those resources.

I’m hoping someone here may have done this recently and has a recommendation for me.
