I realy do feel like giving up as i hav tried asking a feww farmers and they say sorry i already have pest controll.
I think you need to make it clear to the farmers/landowners that you're asking their permission to shoot, not offering pest control. Although in effect, you will be helping to control pests, it's not quite the same things as a full pest control service.
Okay, i'll try, but realy tbh. Who want's a 14 year old to shoot on their land?
same problem here dont think anybody will want people on their land until they look 35
