I took a web design course that included HTML, CSS, PHP and JQuery, I'd like to say I know stuff, but my experience with it is very limited, since I haven't done much coding with PHP on my own. I still do know the fundamentals and more of the language and can work on my own, but my experience is limited.
I could be able to help with more tedious and less complex parts of the coding if you need help.
I also took three years of C# at school, and is the object-oriented language I know the most of.
