I would start by making sure the site validates. Currently your site has over 480 errors! Most of these are the result of using upper-case tags with an XHTML doctype (in XHTML attributes and elements must be all lower-case). Consider either changing the doctype or changing all the tags to lower-case.
I would suggest you first add your site to google, msn, yahoo search. Publish a site map and keep updating the sitemap and the content on your pages every few days to get PR.
I start and make sure the site looks good on all browsers and that it's bug free. Currently I see some issues, a lot actually. If the site looks ramshackle I wouldn't be buying from there in fear that its a scam site.
