Looking for cockatoos

Sulphers, citreons, lessers

looking for 

2x citreon hens young or old, 2x lesser hens preferably older would consider young, 1x pair lessers young or old

Could buy or potentially work out swaps with youngster from cockatoo pairs I have in the future. 

Also intrested in blue eyed cockatoos, red vented and greater sulphur crested not at the moment but I'd like to build contacts who have them so in the next year or two I can obtain young. 

Thanks
