Do I need a broker to sell a SMB?

Hi everyone, my wife & I are looking to sell our home based business this year.

We built from scratch inredactedThe business has grown in profits each year, and now runs basically on its own but my wife still does payroll and management.

Very simple and straightforward business plus, the financial books are neatly kept.

We have 5 employees and 5 vans. My wife runs the business and looking to retire.

Asking price $1 mil.

Do we really need a broker to sell a thriving SMB? Please share your thoughts TY!
