What's your value proposition? Is this a marketing app for companies? Or just some kind of info-app? What problem is it solving, or what itch is it scratching?
If it's for marketing, just charge them some kind of set-up fee and possibly a monthly hosting or management fee. Are there any in-app upgrades or ad revenues? Or a fee to buy it? If so, figure out how to split them.
It's fairly easy to build an app that hosts content. Then you need to distribute it and it needs to be useful and serve some kind of need. I'm not sure a static app would be used very much unless there's a TON of content. You might want to read the book, "Hooked" and see if that gives you any ideas.
