Speed Up Website Loading Time

In testing my site I found that the long time is long compared to most other sites. I need someone skilled in coding, web design, and programming to make changes in the site to help speed it up. Here are some issues that need to be solved: 1) The total number of images on the page is 95 Maybe will need combining, replacing, and optimizing graphics. Replace graphic rollover menus with CSS rollover menus to speed display and minimize HTTP requests. 2) The total size of the home page is 171044 bytes. Maybe for pages over 100K layering the design can help to display useful content within the first two seconds. 3) The total size of the external CSS is 18719 bytes 4) total size of external scripts is 112817 bytes. Maybe where appropriate for any scripts placed in the HEAD of your documents. For optimizing JavaScript for size and using HTTP compression or substitute CSS menus for JavaScript-based menus to minimize or even eliminate the use of JavaScript. I'm open to any ideas to speed up the load time of the site, the website is a live ecommerce site so I need a solid and quick solution. PM me for the URL if you need to look at the site for further examination.
