Starting a small rigging business?

[TridentOne]

Brion-
I'm interested in the possibility of starting a small sailboat rigging business, yet have zero experience in the field. I am a sailor and have owned a few sailboats of my own over the years. My passion is sailing and sailboats and I'm tired of the corporate world. Thus I have been "dreaming" of running a small business like this in the marine industry for sometime now. How long would it take for someone to gain the basic knowledge needed to start working in a official capacity? (average time) The big question is can one make a decent living in this field? (again average rigger with a good client base) Are any certifications required? What type of equipment costs initially are needed? How much does insurance cost? etc. I realize that there are many variables involved in these questions, but if you could give me any related information that would be fantastic. I believe that this field is indeed a true art form and would be very interested in pursuing this career field if I could reasonably do so. I realize you may have already answered these questions in a previous post, if that is the case could you refer me to it. Thanks again.
