Integrate Google App Engine with SimpleAuth

I have a website that is fairly far along in development and right now I am using the Federated Login user authentication system that comes with Google App Engine so that users can login with Google/Yahoo/AOL accounts. I want to give users the ability to login with a few other services such as Facebook, Twitter and Linkedin. Luckily there is a open source project called GAE-SimpleAuth ([login to view URL]) that allows you to do exactly this on Google App Engine. I want this implemented on my website. It should be pretty simple as I already have everything set up for a Federated Login but I simply don't have time right now to implement this. All it should involve is the integration of the SimpleAuth authentication method to my website. What I want done specifically is the basic framework setup, the creation of a login page and then for you to make one example handler that uses the SimpleAuth authentition method to display any data from SimpleAuth. From there I can implement it on all of the rest of my handlers. I am expecting this will take 2 to 3 hours and think that $80-$100 is a reasonable price for that work.
