I currently work at a small company and utilize a corporate AMEX charge card for the vast majority of purchases though the card is in my name and I get the reward points. I now have to order materials through an organization that only accepts Visa/Mastercard; no exception and I can't get the materials elsewhere as it's a required product for a Government contract.

I would like a recommendation for a Visa or Mastercard charge card I could utilize for these purchases as our accounting department is essentially useless and just shrugged their shoulders when asked for help. Total purchases are 50-100k yearly so I'd like something with a good rewards program attached. I can expense yearly card fees to my company, but rewards programs would be on me. Currently have as personal cards SPG Amex and US Air Visa.

Thanks
