Expert Javascript & jQuery

Hi, I have a script jQuery & canvas HTML 5, it's slideshow running auto from image 1 -> image 5. I want customize it, i have a button below slideshow, when i click this button, slideshow will show image 2 -> image 5 and loop from image 1 -> image 5 later. I think if expert jQuery, only take 5-8 hours done it. No milestone, you can do it on your server, and it's ok, i will release a half, and i installed on my hosting, if it's ok, i will release the rest payment. Clear My Requirment and only expert jQuery should bid on this project. Thanks !
