Build a calendar Website

Hi there I am in need of some backend ASP.net with basic Ajax to help speed up a project (html /design is mostly done). A lot of this is rather standard, the site is a -very- basic calendar. No 3rd party ASP calendars /mods please. The requirements are as follows: Standard user signup & Login Authentication (live ID) Standard account management New Calendar/project creation in one of 3 categories, with names required to be unique to the entire site Sub project /calendar creation, any name allowed Adding /editing events to calendar (sub) as a simple form with date picker Privacy settings field (public, private or members only) The adding /removing of moderators to calendars (add /edit events) events will have varying formats, (mostly text) specific URL format will be used to fetch these calendars for viewing Ajax will be used here mostly to fetch data and populate site around user interaction (sliding through months, opening up more details etc) Mod /owners logged in will be able to edit them directly here Public: any can see private: only owner Members: only members single event page
