well,. Yahoo says you've got 9 backlinks:
Yahoo! Site Explorer
But I think Google is pretty much ignoring the hotel sites and webpromotion sites because they´re not related. Then there is a free index site. And the only site that might be considered a valuable link doesn't seem to be indexed by Google.
So looks like you need to get some real backlinks.
Still a little strange, because just 2 weeks ago I put a brand new tiny website online on a new domain, for a group of alergy doctors, really simple website, and all I did was submit it to Google using their submit form. After a week all pages were indexed and it's getting some visitors from Google now. (just like one or 2 a day for now, but that's how a new website with few pages start.)
Which makes me wonder, you registered that domain 6 months ago. When did you submit it to Google?
