Growing beyond a single person consulting business

Hello everyone...
Just wanted to introduce myself... Just found your forum and it seems really interesting.I am Maria Tamis and I am 35 year old. I am here for getting some information.

I have had a single person consulting (Engineering) business for several years. I have more work than I can do and I am turning away new work from existing clients because there are no more hours in the week.

I am looking for pointers concerning the issues involved in transitioning from a single person consulting business to a multiple person business. I have prior experience managing projects/groups back in the old days when I was an employee.

I am not interested in becoming a middleman for other consultants. I want to grow the company so that I can take on larger and more projects.
