|There is a very wide range of things one needs to know in order to|
start and run any business. Making contacts is usually a crucial part
of it, but there are many other parts that are equally crucial.
It sounds like you are just beginning to explore the possibility of
starting a new business. My guess is that you are in your early
twenties, and don't have experience with business other than as
a customer and an employee.
To get started with answering your question here, we need to know
at the very least what kind of service you intend to provide. It would
also be helpful if you could explain why you think you will be able to
provide that service. Do you have special training or experience in
some kind of security service?
