Growing my business

I've had my own business for 15+ years and also work full time as a Controller for a maufacturing company. I spent many years before this working for CPA firms and was surprised at the lack of individual "one on one" time with the clients.  I left the public sector for a private accounting position and built my business by word of mouth. I'm very unique in that I work out of my home in the country therefore, I pick up and deliver to clients making my services more convenient for them.  I've finally reached a point in my business where I'd like to expand and make it my full time job.
