web based calendar

Hi, I own a screen printing company and I need someone to create a web based calendar. Here is my objective: To create a web based calendar so my sales people, art dept, production manager and shipping can view an order on a calender in real time to see where the order is in production. I am attaching two generic screen shots of a calendar I created to show what info needs to be on the daily calendar, and the weekly calendar. I need the option to have at least 10 - 12 different named calendars and each of the calendars to be password protected. For example, one calendar may be for one of my big wholesale accounts and I only want them to have the ability to view that particular calendar so they can track their orders, and upload the art file and upload the file that contains the order itself ( You will see this on the daily calender pic). In addition to that calendar, I need a running like spreadsheet type of list so we can view all the orders in list form. It will have the same categories as the daily calendar (order #, customer, rep, etc). As the orders are added to the list, I would like them to be put on the calendar as the production manager approves that. So, it would work like this: The total list in spreadsheet like form, the sales person would take an order and fill out the list completely, at this point it isnt allowed to go on the actual production calendar. As the production manager approves the order, all that info would show up on the calendar itself. Then we would be able to see it on the calendar and how many orders are scheduled for any given day. If a day gets too booked, then we would simply change the production date on the main list and it would be moved automatically form one calendar day to another. I am attaching a generic picture of what info should be included on the list before it goes on the calendar. Please keep in mind, this would be the screen printing schedule. Embroidery calendar fields will change somewhat. see attached file and it will make more sense.
