The description shows the sell and buy price from vendors. But of course you can't buy HQ from a vendor and at such low craft levels you can't reliably HQ yourself. Still 20k seems pretty high to me personally, those low levels go by so fast I don't usually even bother with turn-ins until I'm a little higher and I definitely wouldn't be spending money on it, but to each their own. When I see out of whack prices like that while doing my turn-ins I'll usually make 2, one to turn in and one to sell, so no don't feel bad about it.
