You'll find many if you do a search for google page rank. however, aside from page rank, which takes a while to improve for each of your pages, I would recommend that you log on to Google/webmasters/ and register the site. provide a sitemap, and start building good back links. Monitor your progress through the webmasters portal. In addition, do the same on Bing's webmaster tools. Aside from those two, I wouldnt bother submitting to any other search engine. You should also submit your site on dmoz.org
Personally i don't know why Google don't just release a site rank lookup for a particular keyword, cause however they forbid it people in SEO will always have to lookup their clients keywords and will always find ways round it.
I hear a lot of hype about a ranking tool called traffic travis http://www.traffictravis.com/ it limits requests to a certain speed so doesnt put too much pressure onto Google, it basically just does what you would have to do to find out your keyword rank yourself, plus its free to use for a limited amount of keywords.
