(I'm looking for) a board for sale

I'm looking for a double-digit plate; if it's under number 30, I'll buy it from you for 8000 and you cover the transfer. If it's above 30, I'll buy it from you for 7000 and you cover the transfer. And I'm looking for a triple-digit plate with slight distinction for 3000, and you cover the transfer. Slight distinction, for example, letter lock or number lock
