Oh No...you may not want to read this Dave ;D LOL
I have given this a little more thought now, yes the old grey matter got jump started.
No aerobatic military or civilian team flies four (4) hours of continuous aerobatics, it is just too demanding.
So, without seeing the flying routine I think you might get ten (10) minutes of aerobatics out of sixty (60) minutes with several full stops and shut downs during the four (4) hours. Now some of this time will be climbing to altitude and doing basic maneuvers and flying to and from the training area.
Now stay with me on this Dave...you said you always wanted to fly an aeroplane...why...damned if I know...but have you thought about this?
Take that $1000.00 and put it towards a pilots licence, ultra light, recreational, private but that is something you might want to look at. Please take the time and talk to some other fellas like Sean and Brett on this forum and get their input on this. I do not know the United States FAA regulations as I am in Canada but these guys will be glad to give you their opinion, I am sure of it. :)
That $1000.00 to me Dave will get you started towards your dream of flight and you have a whole year to save a little extra to add to it.
That is just my humble two cents worth Dave, maybe your dream could be to have your first dual lesson on your 40th birthday and that is your decision and yours only.
Whatever you decide Dave I know you will have fun.

Cheers...Happy Landings...Doug
