JQuery and Javascript Modification

Hi there, I need some upgrades/modifications related to JQuery and Javascript done for [login to view URL] 01. Homepage Slider - Thumbnail slider need to continously move vertically (up or down) and speed and direction should be sensitive to the mouse position and loops - Similar to [login to view URL] homeslider thumbnail. But it needs to be for vertical scroll and no need 3D. 02. Post Back Button e.g. [login to view URL]!pnb-darby-park/, when we click the back button, it should go back to the previous CATEGORY filter if it was selected. 03. Portfolio and Press Pages when rollover on the project thumbnail should be the same where the entire hoverWrapperbg section with magnify glass icon should be clickable to go into the project post. This needs to be done within 3 days. Let me know if you can do it and kindly submit your past sample works related to jQuery or javascript. Budget is within $30-50. Thanks!
