Update and Add features to a PHP Site

I have a Courier Management System script written in PHP/MySQL that I need some changes and additions to be done on. (Kindly go through the demo link below) An in-depth draft of total changes and requirements is attached to this project. Kindly review the document thoroughly before submitting your proposal. Project Rules for the freelancer: The developer must code and send the software files to me or set up a demo site for testing. There can be some last-minute changes I might ask for before the completion of the project. The developer must stay in contact with me so that I can give instructions properly. I am using PHP Version 7.3.6 and MySQL version 5.7, thus the developer must code the scripts to support the respective versions. One more requirement that I have for the booking feature (which would be a dynamic feature) i.e., Rate By weight and volume calculation (Dimensional Weighting/Volume metric weight). My firm has separate rates as per the weight (in Kgs) and Volume (as per cubic foot LxHxW) of the parcel, and the invoice must be generated at the rate that is highest. For example Rate per Kg is Rs. 10 and Rate per cubic foot (ft3) is Rs. 50. So if a parcel is 10kg and 1 ft3 then the higher rate of 10kg @ Rs. 10 should be applied and on the other hand if a parcel is 10kg and 5 ft3 then the higher rate of 5 ft3 @Rs. 50 should be applied to the bill. Project Duration: We are expecting the project to be completed within 1 month (30 days max) or sooner. So if the freelancer is confident about the timeline, only then post the proposal. Project delivery: After the whole project (site) is done and approved by us, the developer shall create a .zip archive of all the files (source code) of the latest approved site, and send it to us. The archive must also contain the .sql file of the tables of the database to be created in our MySql database. The developer must remain in contact and ensure that the site is working fine and as expected on our server as well, to conclude the project fully completed. Attached are 3 files: 1: [login to view URL]: The Main draft file containing all the details of required additions. 2: driver challan [login to view URL]: Is an example format for you to understand what details need to be added in the "Drive Challan" for print. 3: part load [login to view URL]: Illustration of how the "part load book" form must look. (We can provide the actual page as well if you want) Kindly review and confirm all the requirements and let me know if you have any questions or doubts regarding any of the requirement.
