260 Domains in one parcel and one auction??

[JustinMac]

G'day, I have been trying to find a provider who will let me put a single parcel of either 260 domains up for auction or segmented them into 21 parcels of themed domains. Sedo will only allow me to put up one domain whilst linking 5 to it, however this means breaking up the themed domains. Does anyone know of any provider who would be willing to assist. Thanks JustMac
