Couple of handy looking tykes there Sambo.Hope someone near you will come forward,if they do let us know how you get on.Have you got any of your own permission yet?I know it can be hard to come by,but,you just have to keep asking,and,offering your services(labour) during the summer,as farmers always need help during the summer.If you prove yourself to be reliable you should soon start gaining some permission,and,usually when you get some,some more will come along then.Good luck.
