Pitch for debt financing

We want to create a clear and compelling presentation to use to pitch banks for debt financing. We are a barbershop chain with ten locations, and ~$8 million in revenue. Give a quick company snapshot (AUV, average ticket, demographics). Would like to show store contribution margin, cash on cash return for store build out, demonstrate SSS growth and revenue CAGR. I want to make the case that we are still under-leveraged and can handle more debt.
