All excellent advice above.....:-) I can only reiterate the importance of land/quarry, if you think you've got enough, you probably haven't! & use your imagination.....when I first started I put card in my local farm shop offering FREE RABBIT CONTROL.....ok a little artistic licence there lol, but it got people calling! Although many of the places I visited were unsuitable, I did get a couple of real gems from it, one of which led to many more places & experiences.....:-)
If you do find a kind of mentor, make sure they are 'open' to other ideas & suggestions, nothing worse than so
