This can get your fan page killed very quickly. A 1.13M fan page is not something I would want to lose.
@OP: Your best bet would be to either sell it, or link it to a "legitimate" website that you own. If you do not own a legitimate website, get one designed.
Do not market ANYTHING directly on your fan page. Have all of your CPA offers on your website. Your website should be related to the same niche as your fan page. You can even collect double opt-in E-mail addresses off of your website.
If you go the legit website route (which I highly suggest), do not start posting status updates every two hours with a link to your website. When you DO post status updates to your website, make sure your offer is not sticking out like a sore thumb. Based on the niche of your fan page and your website, do not just try to push an offer...give them some decent quality content as well.
If you really want to take this to another level, give the users an incentive to connect to FB using their Open Graph API Protocol. If you go this route, do not break FB's TOS because they will delete your fan page in a heartbeat and blacklist your website.
