Working with another company

This sounds like a great opportunity for both you and the home remodeling company. As with any new business relationship, my advice would be to set a meeting with this person to set clear expectations about your services, pricing, and timelines. I'd express interest in helping each other grow your businesses and see if he would also be open to providing referrals or introductions to clients and people in the community. You could work out a commission or discount on future projects to the remodeling company based on the clients who sign up for a service plan with you. Lots of possibilities here. Good luck and congrats!
