No offence taken, Matt - don't ask don't get! ;-)
I would suggest either:
1) Do some more and post some specific questions, preferably with a clearer diagram
or 2) Get in touch with vex, 101music, SM Contracts, Fusion, T&T, Custom Controls, or another local/london based installer and go over it with them. They will charge either a flat rate for a diagram to suit your brief, or a %age rate for full-consultation. Many will refund the consultation fee if you buy a significant amount of kit through them and/or have the system 2nd-fixed/comissioned by them.
