I'm not gonna put lots of fluff in here, everyone knows that facebook has huge potential to make money especially if you have a viral idea and a unique way of promoting your fanpage/app/group or whatever it may be. Here is an example of a 'viral app' http://apps.facebook.com/pimpitupp/ Each user must accept user permissions to view the application, after they allow the app permissions, the app will post to X number of their friends wall, you can set the number but I recommend 5, I have not lost any apps posting to 5 walls. You can specify a custom message like *facebook persons name* just checked out *app name* and customize it further but those who are interested, I will take you through the steps and set-up anything you need. You need a domain and hosting to run this kind of app, you also need a simple landing page [an appealing image with a content gateway is fine] and that's all. The price is $147, for the complete app setup, you must have a domain, hosting and a landing page, I can help with the landing page side if it's something similar to the app I have posted but $147 is dirt cheap for what you're getting. I will also give some advice on how to promote the app but it's very simple, all you need is an early rush of traffic and every install of the app means 5 more sets of eyes see it plus anyone who visits those 5 sets of eyes profile see it and if you're message is appealing they will check it out and you have got more eyes onto it, you get the point
