Applied for the Ink Unlimited, second Chase business card after getting approval for the Ink Cash this January. Rejected for "business too new," called recon, they asked a few questions (history of the business, what type of business, projected revenue for next 12 months) and I was approved for $3k in credit like many others here. A real, incorporated business.
The low credit limit will make getting the bonus a pain but it's still feasible.
