Please Help - Mac User - Almost Setup, I think?

I have the teamspeak app loaded on my macbook. I somehow downloaded the server program. It look me a while just to figure out how to open Terminal. I think I created the agree to license file. I started by rent a server near my city but haven’t paid the $1.50 invoice yet. Trying to figure out how to get this setup so I can host friends. If anyone could have a short phone call with me or point me to a great video I would greatly appreciate it. my email is [email protected].
