ABS repair service

Hi, I recently moved to a country where I cannot seem to find an ABS repair service. I would like to start a workshop that repairs existing modules or installs new ones; depending on the problem.

How do I start such a thing? Is there a way to train employees, resources I can use? What equipment do I need? Which parts do I need to have in stock?

I know this is not directly connected with a car problem, however I have found your site very informative and would like to know if any advice can be given.
