Realistically gate money would have been nearer £300k by the time you add in concessions, complementary tickets and the sponsors/hospitality. Of that, costs will need to be deducted (Hibs presumably, stewards etc). I'm not saying I don't expect you to make anything from it but I wouldn't expect it to bring in a huge amount of income in and I would expect that a Scottish cup run would far outweigh it in terms of financial gain.
I've not read the full story so I don't know what you're declaring you made from the game.
What was the prize money for winning it, out of curiously?
