jQuery Guru Needed

We have a web app we've developed and it uses a ton of jquery. Overall, it's fantastic. However, we've noticed in some instances it's quite slow due to all the JS. We can tell because if we remove the JS, the page loads much faster than if we put it back in (with the same amount of data). We have a very good understanding of jquery, but we don't know enough to really look at the code, optimize it, and figure out how to make it run as fast as humanly possible. We need a jquery expert to lend us a hand. Our main JS file has around 5k lines of code and we use around 15-20 jquery scripts in various places of the app.

If you know someone or if you are the right person, please contact us and let us know your hourly rate.  Thanks!
