I think it can vary a lot, depending on how far away from a city you are, what sort of things are present in your town exactly, and other things. If there are any sort of LGBT community centers or resources there or nearby, I'd start with those. Volunteer, attend events, get involved. If there isn't, the next question would be how many people you're out to. If you have friends who know you're questioning/attracted to women, maybe you could tell them that you're looking to meet someone. You never know who might know a person who knows a person, etc.
Maybe you could hang out at a local coffee shop reading a book by a known lesbian author (by that I mean known to lgbt+ peeps). You never know a girl might come over to talk to you about it
