Web Developer Required to Complete Amendments On Website

We have currently got a jquery heavy Wordpress site and need to add an animation to a custom scroll bar.
Therefore, we require a fast programmer that can produce the right animation for the custom scroll bar and get it working the way it needs to work.
Ideally need this done today and tomorrow, so if you are unable to do it in that time please do not bid.
All bidders will receive the Wordpress theme and the brief, which outlines what we require.
Basically once you have seen the brief we need you to tell us how you\'ll do it and how long it will take.
There may be a chance of other work depending on how well the chosen bidder completes this job.
