Shaz, have been away for a few weeks so am only just catching up with emails and forums.
There are several companies who will do jerseys with your logo of choice, they advertise in the cycling mags. The more jerseys you order, the cheaper the cost per jersey, this is also true for T-shirts.
If nobody else volunteers, then I will put my hand up to act as a central repository for payments and ordering the jerseys, if we can decide on a logo, colours, etc.
I'll put my thinking cap on vis a vis a logo and see what I can come up with but be warned - I am very fond of the blue-green colour spectrum.
