HI
i have read your requirement. I do understand what you want and i can do it.
I am very familiar with facebook. I have created many fb apps.
Here are some of my simliar samples:
1, A wordpress plugin, when you create post auto share to your fans page.
2, An app you add rss, will auto update post to your gourps and pages when rss update.
3, Album fetch you and your friends FB images.
I believe i am the right person for your project. I have good completed rate. Clients are very satisfied with my work. I will help you deploy and register FB API. Let's talk on skype for more details and start ASAP. My skype is dazakeen.
Best Regards
Michael
