Need Javascript/jQuery guru to customize Calendar widget

We are building a web application for a client, and have located some open source calendar widget code that we wish to use in the app. The code is no longer supported by its developer(s) but is relatively simple. We need a Javascript/jQuery expert to work on this small block of code and have its behavior slightly modified and allow us to get some external control over the widget. The candidate for this should have at least 3 years of Javascript experience. I'm not even going to respond to anyone who doesn't provide in their bid some demonstration of their JS competency. So don't bother bidding unless you can specifically attest to your Javascript skills and we will be checking on its authenticity. This is not a complex project for a seasoned JS developer. We'd do this ourselves if we had the time.
