Whoah Paul, that's a rare request, and a little bit too early for me !

Do you want those plates now, or are you able to wait until mid-June ? I have Hu A plates, 100% legal and ok for transfer, for my YBR250, which I will sell after my round-china trip this spring, 'cause I'll leave China after that.
No idea about the current price though : what is it up to nowadays, more than RMB 50,000 ?

Tell me if you're ready to wait, I'm interested for sure !
