for instance, there *may* be 40% from Scotland and the North, so it would be logical to have it towards the North of the country
If this is the case then Nottingham is a fair location. However I'm not too sure how many are from the North or South etc.
Another thought about costs. Most advertising would be free through the internet or of little cost. Leaflets can be created cheaply to be sent to dealers who want to have a stall pitch so they may send them out with any product orders. The significant cost would be venue. But then I'm not taking into account lecturers/performers/artistes. Can we negotiate lower fees due to first year start up? Actually I'll shut up, I'm thinking now about lots of costs!!!
Dealer sponsorship is another way, The 2006 TalkMagic Convention sponsored by Alakazam Magic, for example. More spondoolies than just a pitch as its free advertising for them - whoever "them" may be!!
