It's actually a whole lot simpler to produce these bags than you probably imagine, I've spoken to an advertising/promotional bag/luggage manufacturer, whom my firm has used before, who can produce from 20 upwards and see no problem with the size or material.
I'm not sure about the logo, but I won't bother Rob unless we have a serious commitment, re. its copyright as Empeg or Rio.
I'm going to be passing their address in Manchester, next thursday, 11th, and can show them the bag, so, if anyone who is interested can post on this thread, so that I can get an idea of numbers for them to cost out, do so, before then.
At this stage, no commitment whatsoever - on your part, or mine!
