L15 - despite your clear enthusiasm for the game, at the age of 15 and with 3 hours logged towards a PPL, this really is a bit premature.
By the time you have the PPL and are ready to go hour building (for what?) no doubt a number of those schools in the US will have ceased trading - especially if they are not supported by a website or flight school listing.
Of course you want to progress, I see you also want an IMC, Multi engine and night QUALIFICATION (it's not called a rating), but it'll all come - in time.
BTW - what's a Vigilant and/or Tutor?
