I am looking for selling business credit card for credit card issuers, where I can both have one-time commission and residual/interest income. Is this possible?

go to commission junction http://www.cj.com or linkshare http://www.linkshare.com and sign up and they'll have credit cards to sign up for to "sell"

go to the credit card you want to get commission for lets say american express http://www.americanexpress.com then go to the bottom and click on affiliate program. it will ultimately lead you to sites i listed above. i believe the commission for american express is $50-$100 per cards are responsible for selling

you have to have a website 1st and it has to be pretty nice looking before you can be approved
