WOW, I didn't expect this level of openness and advice, many many thanks guys!! I am returning to England tomorrow morning, arrive Sunday afternoon, and have exams pretty much right after (Monday morning, Wednesday and Friday). I will do my best to explain a bit more on what it is what I want to do. I'm starting off with one aspect of the business idea, and if it works, great, if it doesn't I wouldn't have lost a lot of cash or anything.
I'll keep you updated and many thanks once again for all your help!
