What do you think of my business plan?

I've just set my mobile site ready for release and monetisation. I have 3 business models concepts at this point: 1- Advertisement 2- Sponsorship 3- Paying customers for the premium service, premium service means access to more feeds and all blogs on te listing, but I'm not sure if thi is a good move, since peoples don't like paying for content, could you please give me some feedback concerning the third option? Should I keep the paywall dor more content or better remove it? Would you pay for the service as a user?
