maybe try an add in donedeal, would be very important IMO to show you have insurance. I shot a load of crows for a farmer friend of mine a few years ago, he was delighted when I did it because he had a high number of calves sick because of them, he had tried absolutely everything and shooting them is the only thing that worked. I just didn’t have the time the last 2 years to do it for him and I told him to ask the gun club or just spread the word because lads would delighted to do it, he wouldn’t hear of it, insurance / claims and the thought of allowing a stranger into his farmyard with a gun just put him off. I’d say this is the case for a lot of farmers. I’m farming myself and I can tell you people aren’t turning you down because of their love for vermin. To be honest I wouldn’t let anyone on my land to shoot if I didn’t know them or got a reference, the whole claims thing and the idea of someone scoping out the place would just put me off rightly or wrongly.
