I wish, realistically its very hard to make a shoot pay 30K won't look at the cost of a keeper these days, wages, cost of suppling and maintaining a vehicle, suppling him with a house think of what that house could earn you in a monthly rent if it was not tied up with a keeper in it.
Then there are the other benefits that a keeper gets these vary from estate to estate but for example these are the ones I got when I was last employed full time keepering more than twenty years ago, dog allowance £2 per week per dog , all my electricity, telephone bills, house rates, no rates now but the lad that went there after me got his council tax paid, milk, potatoes, and eggs all estate produce while not amounting to a vast amount it all helped.
Feeding costs, shooting day costs transport,beaters, pickers up, the list goes on and on.
