Success with a new business card today using link K. Funny thing is that when CS only gave me 3k credit, I said can I transfer credit from my other cards and CS said that I had no other business cards. This was strange because I have two 20k limit cards open under the same name/tax id. Gave him the cc number and he shifted credit over from the card, which I'll be closing because the annual due is owed. CS ended the conversation by saying spend 3k and you'll get 50k miles, so I'm good to go.
