How to generate a personal PDF on the server for KP?

Question

PHP

Task: to create automatically a commercial offer (CP) for customers in the form of PDF, where information will be automatically generated based on the fields filled in by them.
How to receive and process information is clear. What is the general methodology for generating such a CP?
What is the best way to make a technical task for a proger?
What do you need from a designer?
As far as I understand, the designer will first draw the CP, then it needs to be turned into HTML, then the php script will generate it and insert data into the fields in the HTML layout. And then somehow wrap it in PDF.
So?
