A category killer would be a .com.
You could probably outbound this to a liquor store, especially one that advertises on billboards .... if they want to upgrade from some-long-liquor.com to your short Liquor.biz. But I have no experience selling alcohol names so I have no idea. I also have no .biz experience so....
If you were to outbound it I'd ask for like $5K - but you might have to hustle real hard to get that. It's unlikely anyone would ever come to you. This is a straight up sales hustle.
