I had an idea to call diff

I had an idea to call different video companies here and ask for their prices (be it hourly or flat rate) to get an idea how the market in my place is. I love the idea that you just have an hourly rate for shooting and editing but my question is how do you come up with that number? If I am going to talk with future clients I want to be consistent just like what Earl said and probably adjust accordingly when I get more business coming in and I get better. I think I need to eat and rest for now coz I’ve been reading non stop in this forum and been bombarded with tons of info haha ; )
