Generate LaTeX PDF from PHP

I am looking for a freelancer who can generate a LaTeX PDF from PHP for my invoice generation needs. The main purpose of the generated PDF is for invoices. I have a specific design or template in mind for the invoice and I will provide it to the freelancer. Additionally, I require automatic calculations to be included in the PDF. The ideal freelancer will have experience in LaTeX and PHP development, as well as knowledge of invoice generation and automatic calculations.
Currently the PDFs are generated by converting a query to HTML and then converting the HTML to PDF using MPDF.
