I got my OEGB from a guy down ther road from me, I got rid of all the roo's or I could hatch you a few. I got 6 chicks for $10.00 so they were a good deal. They shouldn't be hard to find though in your area. Have you tried looking in the carolina bargain trader, or go to cbtmagazine.net and search the pet section. There might be a few in there.
I have been looking for a gamefowl roo for my 3 hens for some time. They go fast here in NC. I am hatching some pumkin husley to get my roos, hopefully by Thursday they will have hatched. I got my eggs from Green Fire Farms, they are pricey but out of 8 eggs 6 were fertile. Their website is Greenfirefarms.com. You can also get trios from them. But shipping is expensive for adult birds.
Cackle Hatchery has OEG STD which are larger and more gamey than OEGB. $40.00 for 5, I have been trying to contact them for availability but so far no luck.
