Mine have yet to start laying for the season but I'll have some soon, I hope, and was planning to sell as hatching eggs. The three hens came from Keith's Orps in Berkshire (
http://keiths-orps.co.uk/) who has beautiful stock. They're just coming into their second season (i.e. hatched 2012) which I think is why they're later coming into lay - they were laying up until Christmas.
I got the cockerel from Preloved and he was a hatching egg from breeders in Kent. Less prestigious lineage but he's a fine looking boy. He was hatched last year and is a little over exuberant at the moment (currently have one hen in the kitchen to recuperate as he's trodden her sides badly). Happy to send you photos of the group if you want.
Just, as I say, they're not actually laying yet unlike my gold laced orps who are laying their little hearts out so it depends how desperate you are to get going - I'd want to double check fertility first. Otherwise you could straight to Keith's Orps - they're not cheap but his breeding stock is lovely (he doesn't show but he has two pens of buff one for showing, one more utility).
