Design integration with php + Custom addon

Hello, I'm looking for a professional PHP programmer to integrate a webdesign into php script + to make a custom addon for the script. The webdesign is so simple as the website is simple too (not too much design). But I don't want to have any error with the integration, everything should be 100% done! I will test it with all the web browsers available. the script is this one: [login to view URL] Custom addon: Ok, this script has an option, that even if you dont have a website, you can add your pixel and when someone click on your pixel a popup page opens and show ur pixel (but in the original size format) + description. I have canceled the online payment, so all the pixels will be added by me from the admin panel manually. What I want is not to show the original image size in the popup page, but to have an option that who want to have a popup page will be able to upload another image to this popup (maybe a flyer or a poster, etc..) So they will have 2 options when they want to add their pixel (with link which is already there) or without a link (also its already there but they can upload to the popup page a second image other than the main one. The addon should be added in the admin panel where i add the pixels manually I'm looking for a PROFESSIONAL programmer who has experience and familiar with the 2 things I want. Please dont add your price if you think you cannot complete this project 100% without any error.
