Update old php/sql website with lots of issues

Closed

Description

I have inherited a website that the original developer abandoned and that didn't know anything about security. I took this on as a favor but I am not a full time developer. It is a PHP/SQL based website with two backend applications that the owner uses to populate his website. The problem is that it was a custom built backend that has NO support. The site is wide open for attacks, especially sql injection, which has happened frequently. I have plugged a few holes and moved the site from the owners original host that had no server side security to my own host (Blue Host). The php is filled with deprecated sql syntax and was built on PHP version 3, which is not offered by hardly any reputable hosting companies anymore. It runs on PHP 5, but with a lot of errors. The biggest visual error is the rotating ads function. If you have the cajones to tackle this at a reasonable rate work it until it's fixed then let me know what you would charge. Attached is a single php file for you to review to see the mess you are going to be getting yourself into. If you need to look at the live site more closely let me know and I will send you the link.
