Happy(?) Dilemma

What to do?
Looks like I have two very talented young horses.
Maybellene is heading for the top levels in dressage
..and Paeon? How far can he go? He keeps stepping up to any questions asked of him in eventing; dressage and jumping!
Heath suggests I put him in his Performance horse auction at the end of November, but that means an expenditure of another couple of thousand dollars as I'm no longer able to do the riding myself. That's not a justified expense at this level of his experience and performance. Maybe after an autumn campaign next year when he's stepped up a couple of levels...but how to fund two fine competition horses?

Any suggestions??
