Search and Compare PHP Script for a Wordpress Blog

Hello Freelancers, I run a personal blog where I review mobile phones and tablets. I am currently looking for a "Phone finder and Comparison script", exactly like the one at: [login to view URL] I am not very crazy about the looks of the thing, but regarding functionality, I need a script that works exactly like the one shown on the [login to view URL] site above. The script has to be in PHP and since I am going to be using it on a Wordpress site, I should be able to run it without any issues from within the blog. Someone with good PHP experience should be able to handle it easily, as all it needs is a data base with the specified fileds and then upon selecting the devices to compare, it just has to read the database entries and populate the fields. Also note that there should be a convenient way to add newer entries into the database as and when needed. I don't need a stylish looking backend interface to add new entries, but the method of adding new entries to the database should be simple enough so that someone with no programming experience should be able to update it with new entries. Adding data entries manually through phpMyAdmin will also work for me. PM me for any more detail that you need. Thanks PS- I will be launching several product and news related websites shortly, so if you are able to deliver the job satisfactorily, I would like to engage you on several custom PHP coding websites after that.
