Affiliate Marketing Secrets

I dont want to give too much of the idea away. Not because it is secret but as it is still very much on the drawing board. However, it is designed to be a phone line resembling the “Samaritans.” The finer details of my idea makes it not like any that exists so far and I know there is a (non-profit) market out there for it. So, it would need a phone line.
How much would this cost to set up? Or, do you have any advice on who I could contact to find out?
Thank you, in advance.
