flying
It seems you're asking for the eggs & the chicken money !
1-Your PPL never expires, however you'll need to have some current flying to keep on going up...FAA Medical should be done quickly (within a day or so), however TSA approval might taker longer.
A good school in a clear weather area as far as I know is in Florida...Depending on the pricing (wet or dry), some well known schools like American Flyers, ATP flight school, Delta Aviation Academy...from the top of my head,these school should meet what you're looking for...hope that helps.
