Data push to Google Apps

The app is intended to regularly push a one-way sync of Salesforce Contacts and related fields to Google Apps Shared Contacts.The desired end result is that all of the contacts in Salesforce (which acts as the master repository) are pushed nightly into a specified Google Apps domain, into the Shared Contacts. Google Apps users within that domain can search their contacts and see the Salesforce contacts and relevant data in their list of Contacts. I have a detailed spec that can be used to consider quoting.
