If you really want to have every page as small as possible then you need to investigate CSS a bit more, as CSS is cached by the browser and therefore reduces your load. All those border="0" for images, or all the cellpadding, cellspacing and so on for tables could be defined in your style sheet instead of repeating those everytime.
And look at this example snippet in the page:
<td><div align="right"> 38,967 </td>
That should clearly be
<td class="right">38,967</td>
with the properties text-align, padding-left, padding-right set for your td class in CSS.
I guess you may find more places to convert from HTML to CSS for shorter pages, if you do a detailed inspection. Maybe you find that you can put the image width and heights into the CSS without making your output much larger. And BTW: font tags are deprecated, so you should replace them by proper CSS too.
