Build me a web app

Job ID: 35536431

Budget: €250 – €750 EUR

Hello!

I would like to create a custom web application, which plays with xampp on a windows computer and can be operated by the user mainly from a tablet (obviously via a web browser) but also from a computer. I want it to be in php (maybe laravel if you prefer).
The application concerns the operation of a factory in which customers unload material at specific positions (numbered from 1 to 30 for example). I want the employee to register in real time from the tablet which customer, unloads at which location and how much material. Then you can monitor this from a central screen (e.g. from a computer screen via a web browser) so the app should be responsive to all devices.
I want a database with the following 4 entities:
1. the customer, which includes name and phone number (optionally address, email, VAT number and notes)
2. the load, which includes position number(1 to 30) and customer(entity 1) mandatorily (and optionally notes). It also contains material quantity, which is initially 0 and then configured by entities 3 and 4 below.
3. the addition of material to a load, which includes date, amount of material added and load mandatory (entity 2)
4. the processing of material from load, which includes date, quantity of material removed and processed, the load (entity 2) concerning mandatory (and optional 2-3 other fields)

I would like to have an authentication system with two kinds of users. Those who will only be able to see the loads, and those who will be able to edit them (add - delete - edit). Each user will sign in with a username and password.

Finally, I would like to give you a responsive html-css file (I will create it, I am a front-end developer), in which, at specific points, 2 elements from the entities above will be inserted. The customer name and the amount of material contained in real time in each position (from 1 to 30) so that each device can see it in real time. e.g. in the html element with id "position-1" the information for position 1 will be inserted. Correspondingly in the html element with id "position-2" the information for position 2 will be inserted etc. So php needs to insert these information at the corresponding html elements.

Please let me know about the cost, and the implementation time.
