Did you have them sign a non compete or non solicitation agreement during onboarding?
Non competes have no legal ground in most states. I don’t think you need to put steps in front of your employees following the same path as you did. Instead offer the assistance you didn’t have and allow them to show you what they can do with their own location.
If an employer is doing quality work, they have no need to worry about a new competition across the road. I think you should worry about building for yourself a fantastic company that is way above completion. The customers who value quality over mediocrity will always remain loyal to you.
