Thank you so much to everyone who's pitched in on this discussion, I can't tell you how much I appreciate the advice. I've got so much to think about now I'm going to print off all your posts and have another look through over the next few days.
Just thanks again everyone,
Stephen Williams, Brian Drysdale, David Mullen, Freya, Phil Rhodes, tenobell, and Michael Collier,
you've all given me fantastic advice and I appreciate it.
