Make a time slot page

Every Friday and Saturday i deliver furniture in my area. I am looking for someone to create a website that I can inform the customers in which order they will receive their delivery.

Once I have completed the delivery I need a very simple way to remove the delivery from the front end or mark it complete in order to provide the information to the next customer that they are next.
I should have a simple login area that allows me to enter the customer id in the slot so the customer can identify where they are on the list.


I want to be able to login to a panel and in the panel are slots In each slot I will write the Customer Id and choose a time window for delivery
Once I have written all the customer id and time slots in an individual slot on the page. I want to press send and then it shows up on the front end of the customer page.
Then when Friday comes and I am doing the delivery I want to be able to log in and simply click on one button and the slot is removed or marked completed once I am done with that delivery
I only do delivery on Friday and Saturday

IF you can do this type: I am ready now" at the top of the message
