Help with Google Calendar v3 OAUTH Service

I need some help implementing Google's calendar API using the new version that requires OAUTH2. Basically I need a Service layer written that will do the following methods. - Authenticate (Generate a token based on the OAuth login). I will provide the username/password because this is a service I am using one login that I have setup in the app console. - Insert Event - Update Event - Delete Event I do NOT need a UI, Controller, Model or Views (I will build those myself). All I want is help writing the code that connects to Google's API. Anyone will experience that could help out with this, I am losing my mind :( I don't have a lot to pay for this and I am sorry. I just need help and hope someone out there knows how to do this and can give me some direction.
