API Integration

This is the API integration for a website which supports a mobile app. I am looking for someone who can integrate the following services API to the website. 1. Google docs Integration. 2. Dropbox Integration. 3. Evernote Integration. 4. Facebook Connect. 5. Twitter Connect Google docs, Dropbox, Evernote are Sync services & Facebook Connect and Twitter connect are used for Social sharing (verses, notes etc) For SYNC services: (1-3) Docs in a particular file name (with date and time in the .doc file name itself) system will be only retrieved into the website. the HTML of the website is created. We need someone who can pull the data from the above respective servers and show it on the website. We have a common database which the website and the mobile app shares. So once they sign in in the app it should be automatically signed in the website and vice versa.
