Hi, WolfPony, and welcome to Susan's. I will answer your questions from my own perspective.

This depends on a number of factors - where in the world you live, if you have insurance that covers your T, what kind of T you decide on, etc. But, it *can be* expensive for some guys.

You can get a metoidioplasty with the vagina retained, but I don't know about the urethral lengthening. It wouldn't look like a "normal" vagina with urethral lengthening I would imagine as part of your plumbing is re-routed and covered with skin. You would need to speak with a specialist surgeon about this.

Even just a little penis that you could pee from may not be attainable. The surgeries are costly, and there is a high chance of complication with urethral lengthening - but it's do-able. Many guys have had it done, so just making you aware of the risks.

As much as I want a flat chest, I think if I had huge scars, it would make my dysphoria worse. My breasts are a C cup. If I lose weight(im kinda chubby) I could get to a small B cup. I want to start transitioning as young as possible. I will go to law school when im 18 and I will probably start transitioning after I graduate.
I doubt with a C-cup you'd be eligible for peri. Double-incision is pretty much the standard for that size - but I also don't know, because I've never seen you.
The first step will be seeing a gender therapist - especially seeing as you're under 18.
