it took me ages to get the first positive reply after sending 260 letters but the strange thing is once you get the first one the others seem to just start rolling in.i took on another 2 small pieces of land last week and im getting to the situation now where i will have to turn anymore down.a tip that is worth considering is buy yourself a couple of dozen mole traps and offer your services as a mole trapper as well ,i dont know why but farmers seem to hate moles more than pigeons,rabbits rooks crows and anything else you can think of.so stick at it and you will get a shoot in the end.hope that helps a bit.ps i only pay £1.99 each for mole traps so its not a massive investment when you consider the cost of the rest of the gear.
