I would be happy to refer you to the U.S.A. American Express Business Platinum Card 100k offer.

This is the Business Platinum USA card (main benefits, 50 percent back on selected airline points redemptions, 10 free gogo passes, $200/year airline credit, centurion club, 1.5x on transactions of $5k or more etc.).

The sign up bonus is up to 100k membership rewards points as follows: 50,000 points after spending $5,000 and an additional 50,000 points after spending an additional $10,000, within the first 3 months of card membership. The offer bonus will contain the standard Amex exclusion if you "have or have had" the same product.

Thanks!
