Offer your hands on a shooting / deer estate for experience, hang around & help out. Then work on a farm, in or around the estate .......one thing leads to another. It may be self rewarding, but dont expect a lavish life style, for a few years..if at all.
Get a collage appreniship / trade of some use in the field..fabrication, engineer,building, auto electrics etc. Then you be of use too They'll find ya.
