Hence wanting to get more views here, KH. As i've mentioned already, i'm not expecting a pot of gold or anything like. I'm using this forum in addition to personal contacts to gather information in a kind of feasibility study. If the result of that research is that i find out it's not feasible, then that's tough and i need to look in a different direction for my career change. I'm not under any illusions that it's a lottery win.
