I would recommend getting to know an entity first, working woth them to see if your energy is compatible, and then considering a pact. You don’t need a pact to get most things done. You do need some development of astral senses so you can communicate.
You’ll want to get your spiritual hygiene sorted out, and start work on developing your astral senses.
Then when you can know you have a decent chance at avoiding impostors and parasites then try the first contact guides we have on here.
