hi there,
I work on mac (espresso/cssedit combo), know the system very well, know the job very well. i worked on the similar jobs with some web design companies from serbia, so you can tell that I'm pro, I'm always online, have Skype account, and I am fluent in written and spoken english. My html/css files are always compliant, I never use tables (even not for tabular data). I have basic knowledge of php/mysql (i'm a fast learner), and I can integrate just about every jQuery/JavaScript that can be found on the internet. I used RapidWeaver to make my first website, so that wouldn't be a problem. The only thing that could be a problem is that PayPal doesn't operate in Serbia, but I will find a way to overcome it.
Hope I'll hear from you soon. The price put here is totally negotiable, i didn't want to go below your requirement of $250 :)
