Hey, I had been hunting nearly 35 years before I got my first permission, not that I wanted any in my younger days..
Like Ricky highlighted, it may just be the start, word of mouth with farmers is better than any advertisement..I started doing mole control in the early nineties, spent loads of money for adverts, cards, phone calls, got limited response, the number of times a farmer pulled up when I was in the field and gave me work was unbelievable, and the farmer I was doing work for saying the next door neighbour wants some moles done...I ended with with over 20 farms to control moles on,
