Servie Website

I need a website where it will notify people of their coming events. For example, a lot of people forget birthdays, anniversaries, and other important dates. This website will allow people to get a service where the website will call, email or text messege them when the time comes. People can pay say $5 to get something notified or they can subscribe for a year (let say $50/yr) and get unlimited notifications. People can go in, put their credit card info, choose if they want pay per service or yearly subscription and sign up. After sign up, they can add an event and they can choose what kind of service they want to get: sms, email, or phone call. Or they can choose all of them. They can also set up which service will notify on what days. For example, let say I have a friend's bday coming up in 2 weeks. I can tell the system to remind me via email 1 week before the event. Please put read on private messege board so that I know you have actually read this description. I a lot of people don't read the details and put bids. If the word read is not there, your bid will not be considered no matter how low your bid or how good your feedback is. I can also tell the system to text messege me 2 days before the event and call me on my phone a day before the event. You will also be doing the designing for this project. The design is going to be a web 2.0 design. Nothing from the 90s. I want it to look web 2.0. I'm willing to do with PHP or .Net (not ASP) on this project. I really have no preference on either languages. Whatever is faster and can give better results, I'm all for it.
