Moved this one to the design marketplace Tim, and will send a PM to the printers we have on the forums for you, it's only a couple at present but I'm sure they'll be able to give you an idea about how achievable this might be. I'm guessing they'll need to know proposed size and number of pages to give you any sort of idea on price though...
You'll have to have 8, 12 or 16 pages Tim as printing needs to be in groups of 4 pages (think A4 folded = 4 pages then another sheet stuck inside & stapled in the middle = 8 pages and so on and so on)
I would personally suggest asking both to perhaps PM you and give the job to whoever your preference may be price / service etc rather than risk starting a unhealthy public bidding war, but completely up to you guys that are involved.
I have personally used Neil before and can certainly vouch for him but that's not to say flyerboy_uk won't also give a good service also (doing my best to be diplomatic)
P.S they are trade prices so don't forget to put your mark up on it before sending to the client (you could always ask Greg to move this to the private forums if you worried the client may stumble across it)
