How to get CA C10 license

I want to start up my own fire alarm company. I have 20 years of fire alarm experience as estimator/designer with NICET certification. How can I get a C10 license without the electrician experience? I know multiple burglar alarm companies whom have C10 license and I know there’s no way they have an apprenticeship program under their belt or the required 4 years as a journeyman.

How can I make this happen? Any help much apprectiated.
