Optimise website - max 2 hours work

[login to view URL] is already 88% in page speed and 75% in yslow in [login to view URL] i would require an hour or two.. help for defer parsing of javascript, leverage browser caching. The cache should remember the logo and header and footer the permanent images for longer duration, and all other content for shorter duration.. Whenever someone hard refresh (CTRL + F5) the new site with new content should get loaded. All other things we need to do so as to score full score in gtmetrix pagespeed and yslow with all parameters Since in some computers site is not loading properly and in some systems not at all, i hope doing this will solve issue permanently, but in case not, we need to rectify the same. Also you need to get me helped with setup of ftp so i can also understand how to manage things. Budget for this is max $ 10 to 20(since this is only relationship building project, you can take it that way) For talented freelancer, i will love to continue with you as long term projects. Once we finish this project, the another things will get it rolled.
