Lead Generation

I am helping my wife start a freelance bookkeeping business. She has nearly 20 years of experience keeping books for small businesses, working with owners directly, as well as staff accountant for a company processing payroll for 800+ employees. Experience is specifically in construction, RE development, and a cable company. She is ready to go out on her own.

She is not a cpa and will not be offering tax services. Extensive knowledge in quick books and will be getting her certification.

As an experienced bookkeeping business owner, what are your recommendations for getting leads? What type/size clients do you recommend?

Thank you
