Customer database and online calender.

Here is a brief for what I'd like, there may be a few edits as we go along. Part 1 A customer database and detail entry page. Example I login to an admin page on my website. I enter a new customers details First Name: Surname: Address: Town: Postcode: Telephone: Transmission: Part 2 I need an online calender, for example google calender. It should have a daily view and a weekly view. I need to be able to make an appointment for a customer from the customer database (part 1) This should happen from an admin page, for example Admin Calender First Name: Joe Surname: Bloggs Appointment date: 25/12/08 Appointment time: 9am Appointment length: 2 hours When entered this information will appear on the calender. I need to be able to print the weekly view. I'd like the system to operate quickly. I have mysql database. Any questions please ask.
