I'm new to Freelancer.com, hence the low price bid. I've made extensions similar and more advanced than this already, I can send you example with source code for some of them. I'm fluent in English, living in Europe but without permanent job as I'm finishing my studies, so it's not problem for me to be available anytime.
I set the 3 days limit just in case, but honestly this could be done in one-two days.
