1. You are making a big mistake in putting your title at the end you should move it to be the first tag after the: "charset=windows-1252">"
2. You have not included any of the keywords that you are going to target in this page.
3.You are just using too many keywords in your meta tags. You should stick with whatever you are going to target.
