We all have our hourly rates for integration based on our market, overhead, level of service etc..

My question is about work out of our main scope. I just put electronics in for a theater in an existing room, now the customer wants to turn it into a real theater. I'd like to do crown, columns, seating riser, panels, granite, etc….

In the past I've used one of my contractors and have charged for my design and consultation time. Now I have an employee that worked for one of my contractors and can do all of the work in house. How do I charge for this, contractors don't charge integrator rates and I don't charge carpenter rates. is it worth it, or should I just sub it out like normal?
