New to process serving.

Hi everyone. I'm looking to get into the process serving game. Starting my own buisness I'm from Ontario Canada. I have some questions I need answer to before I get started is there anyone in here that could help me ? Things like. How much I should charge for services. How much to charge for kms, do you bill the client for the cost of commissioning affidavits. What kind of insurance I should have for myself.
