1. You are missing both keywords and description meta tags
2. You are loading several jquery libraries, different versions. Is there a reason for this?
3. There is this text at the bottom, "Private and Terms of Use", which is not a link. What is it supposed to mean?
4. You are using inline styles A LOT, like "<form method="post" id="sendEmail" style="font-weight:normal" action="emailpagedo.php">", <label style="padding-top:10px; height:22px;"><span class="error" style="display:none; color:#FF0000; font-weight:bold;">*</span>Recipient's Name *, this is not cool dude!
5. As @Thebigboss said, using tables for layout is definately not good, especially for a public website.
6. From all those many different PHP files referenced from the home page, it seems as if you are using vanilla PHP? If the answer to this is yes, then congrats dude! BUT, you better test the security of your code till you drop with fatigue, for that is the single most major weakness of vanilla PHP.
10. At the bottom, Term of Use should be Terms of Use
11. And I noticed something else, which I will email to you in a minute
And @JDSKKJ, tables are slow to render on the browser, that's one of the things they did to anyone.
