The html errors are not too bad but to the search engines they definitely can be, there's a table that's not closed. Get a /table tag in there.
- get a google webmaster account. create an xml sitemap, submit
- fix errors it reports. If you can't you need to get someone to do it because that table tag is a good instance of something that should get fixed.
- if you're allowed point to your site from your ebay site
- buy an ad on craigslist for the link
- this page doesn't end the head section, that's a killer tag to be missing

- the title tags, content and url re-writes are beautiful
- could stand to beef up the h1/h2/h3
- instead of using google link: use the private one in the webmaster area, shows a lot more
Most important: put every page through the validator. Fix all missing ending tags, whether table, body, whatever. Those are killer because the algorithm gets to the end of file and never sees any content.
