Roofing Contract

Howdy all, I've been doing low-cost handyman work in my business for the last several months. I just got licensed as a roofer and would like to get started in the business. However, I want to make sure I have a good contract prepared so that when I start getting clients, I can make sure I'm protected. What would you all recommend as a starting place? Do you have templates you've used for client contracts? Thanks in advance!
