Bug fix in a PHP to PDF web script, must already know mPDF librairy. URGENT.

Hi, this is an urgent project to fix bugs that I'm unable to fix myself. If you can’t start right away on it please don’t submit your name. This is a very urgent project. The budget is set low currently BUT the faster I get this solved the more I will give in extra at the end. Extra can range between 150$ to 500$. In fact you need to start right away to fix the first 2 problems described in the Word document before I choose. The first one that send me back a PDF that work correctly because the problem is fixed I will pick you as the winner and if it’s really fast I will add extra money to this. If you’re not OK to start without me choosing you before please don’t submit your name. To be sure that you will get paid, I’m asking you to send only the working PDF as a proof that my problem is fixed. Then I will choose you as the winner, you submit me the php files fixed after I test it and confirm that it’s correctly fixed I will paid + extra if it’s quick. The faster I get this fixed the more money I give. If your not OK working like this please don't submit your offer. You need to start this right now before I choose. The project is already done in PHP with mPDF librairy. Thanks
