Just spoke to the main man on the phone, and he was very personable.
"What colours do you have?" I asked.
"What colour is it you want?"
"Dark/Forest Green if possible."
"Sure we can sort something out"
Pretty obvious to say, but they expect the frame stripped down and free from oil and grease, if they have to degrease it themselves then they charge extra. Heading up there in a bit.
I will of course report back on the rest of the process and pricing, and pictures too.
