Booking delivery php script for courier/transport

I will try to explain it as best I can. I (the courier) must be able to add new clients to the system - Username and password. We do deliver different days, with different timeslots depending on what zip code you live in. Heres an example: Area 01 could look like this. Zip code: 4700, 4800, 4900, 5160, 5200... etc. Monday: 08:00 - 1400 Thursday: 10:00 - 12:00 Saturday: 09:00 - 11:00 ------------------------------ Area 02 could look like this. Zip code: 8200, 8500, 8560... etc. Friday: 10:00 - 12:00 Saturday: 10:00 - 15:00 ------------------------------ Area 03 ... and so on. Now this is how its working for the client. First the client must login first. Now the client must fill out some info on the delivery address... Name Address Zip City Info ... Depending on the Zip code - The client will only be able to choose from a small list of delivery dates and time slots (just like a described above). They can't choose a date before 2 days after "this day" - So if they login wednesday, the fastest delivery day will be friday or after that day. Sunday is our day off, so that day will not count. When the client press submit, I will get an email with the info... If it's possible, I would like to get a full list of all deliveries the day before the delivery day. and I would also be able to login somewhere, and see a calendar with all the deliveries in the past and in the future. Design doesn't matter, I will have it designed myself. I think thats pretty much it :)
