Learn to skateboard, what to start with?

I'm an 18 yr old girl, and I've always wanted to learn to skateboard but never got around to it. I mainly just want a faster way to get around campus this fall, and I'm not interested in tricks right now, but what should I start with? Like what kind of board, shoes, equipment, etc. and where to get them? I don't have much money, so I'm just looking for essentials right now. Thanks so much for any help.
