Does anyone know how to get started being a ghost hunter?

I’d like to start my own group to conduct investigations of places in the area where I live. I watch a lot of the ghost hunting shows, and I was wondering where I could buy the equipment that they use/what all would I need? I know in order to listen to the EVP’s (electronic voice phenomena) they have some sort of computer program to review and enhance the sounds from the recordings. PLEASE ONLY SERIOUS REPLIES :) I know a lot of people thing ghost hunting is “nerdy” but this sort of thing is my bag baby!
