Project 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.

I am going to create a Development copy of the website to give access to. The owner does not want me to give access to the actual live site. The url of the live site is www.webrodder.com. I can also package the site up along with the database and upload it to my google drive for you to download. I would like to keep the project cost at a max of $650 US. Most of the the project will consist of updating the code to be php 5.4 compliant and to remediate all the SQL deprecation and security issues. The over all look of the site must remain the same except for a few changes that the owner would like to change like the article viewing area size and fixing the rotating ads.
