How to charge!

Hi guys, my first post..

So i was wondering, i’m opening a small Computer service business mainly reparing, upgrading, home networking and computer sales along with a few other things for now. As things progress i will expand. so basically what im seeking is like some kind of guide t pricing, like howmuch to charge for services. I’ve gotten some help from others but they all tell me charge what ever i like whick does make sence but still… is there like a website or giude where i can get an arverage of what service costs are like ?

Thank you!
