I can begin work immediately. I have 4 years experience with Full Stack Web Development: HTML, CSS, JS/JQuery, Bootstrap, SQL/MySQL, AJAX, PHP and Frameworks (CodeIgniter, etc).
Instead of DOMPDF I would use MPDF, which is much quicker and has some CSS3 suppport. Depending on the report size and requirements it should take me roughly 4 hours to complete.
Please contact me for further discussion.
