Directory App for Facebook

Hello, I run a small local Social Media company and I am looking to add a facebook app to my Facebook Business page. I want to add a directory in which local companies can add their Facebook page to the directory. Some things I need: - Ability to add categories - I the admin must add the companies via backend - The listing for a company must allow me to add the following: Title of Company (when the title is clicked the clicker must be directed to companies facebook page) Description of company Phone Number if available Website if available - There needs to be a form for business that wishes to be on the directory to contact me. I just need: Company name, Contact Name, Email, Phone Number. I plan to add features to the app as the directory grows. If you can provide me a sketch of how you will create this app or offer suggestions that would be appreciated.
