Moving business credit card

We currently have a few credit cards in our business with Wells Fargo. We used to bank with Wells Fargo but got tired of the impersonal relationship we had with them, so we moved to a local bank where we have one point of contact (big fish in small pond). We have left the credit cards with WF, but are at the point that we'd like to move them somewhere else. We spend about $400k on the WF credit cards so i'm sure other companies would love to have the business. Does anyone know if there are incentives from other credit card companies to move this business to them? We get a ton of points with WF, we also have Cap One credit cards where we get more points as well as cash back.
