Gliscor: 400-450k,
Umbreon: 700-800k after you fix the EV's and lvl up (Put in full 252 hp and split the rest between def, spdef or go full 252 spdef),
Torkoal: 350k trained
These are just estimate prices, you can always ask for offers before setting your price up. Also, that's a very nice umbreon, great catch!
