I am attempting to join a couple in The Life or meet a woman in it so I can build with. How do I accomplish this in Indianapolis, In?
But I'd caution you to re-examine your language and what it might indicate about your expectations. Polyamory isn't some porny sex cult that we initiate people into - it's just a way of having a relationship. If you have a fantasy about what polyamory would look like, or what type of polyamorous person you're looking for, consider doing some research that helps you think through how realistic that fantasy is.
Remember that all people are individuals, whole and dynamic, and no one exists to be your gatekeeper to polyamory. Go out there and be a human dating other humans; treating it like anything else will be an exercise in futility and risks ending up with you being frustrated and other people feeling misunderstood or objectified.
