How do you start a production co to produce plays workshops and musicals?

Start small and be patient. Get a group of talented people together, find a space and a vehicle, get some community support (banks, businesses, no donation is too small- it all helps,) then mount the play. Start with non-musicals because they are far less expensive to produce. (1) Do the very best production you are capable of doing, get lots of press on the performances, then make sure that for weeks and months afterward, eveyone hears how wonderful the production was. By the second or third production you will have built a following. Also, as you are beginning, consider using plays that have a role or roles for children. They have a mass of relatives who will buy tickets and talk up the performance. I speak from 18 years experience with a company in New Jersey, and now working with a rapidly growing theatre company in Florida. Good luck! 1. One notable exception being "Crazy People Incorporated" (http://www.CrazyPeopleIncorporate.co.uk) which has and all-women cast and tells the story of dealing with some of the mental health issues which can result from childhood abuse. The entire musical including script and backing tracks can be obtained free of charge for non-profit organisations.
