Hello Theodorius, I have looked at the source code for the page and have a clear understanding of how I would implement this. It is no more than perhaps 4 hours work. I have a lot of experience with jQuery, having used it extensively in my last job. Although I have no reputation on this site (we all have to start somewhere!), if you choose me for this job, I'll provide you with a professional solution quickly.
Thank you,
Robert Clouth
