Umbraco with integrated social-authentication and YouTube/Vimeo API

We are currently in the process of creating a video-portal. Using .NET and the CMS Umbraco we wish to create a platform accessible by signing in with either Facebook or Google. A user should be able to choose/upload videos via the YouTube API and add them to the website's stream by connecting to his/hers Google-profile either in the signup process or after. Furthermore, a user must also be able to connect their Vimeo profile to the account, and view/choose videos, from the users Vimeo profile, to add to the websites stream The assignment is split in 2 parts. The first is creating and integrating the signin-function with Umbraco’s .NET membership provider. Second part of the assignment is adding the functionality for the YouTube API / Vimeo API. We’re not looking for any frontend development, as we only need the functionality described above. For the same reason you are not required to deliver anything but naked HTML and the functionality described in C#, integrated into Umbraco. We expect you to deliver a fixed budget, a date of when you’re able to begin the project, and an estimated completion date. Please only respond if you're willing and capable of completing this project. Questions are welcome. Thank you.
