your domain name will rank quickly, due to it being the only listing with that name... really its your keywords you want to be tracking as a potential client is more likely to search "window cleaner + location"
rather than your biz name.
Try adding backlinks every day, start at around 10-15 per day. Easy ones to start with are links from blogs, type into Google window cleaning blogs, read the blog then add a comment, make sure the comment is useful and to do with the blog so the link is more likely to stick. So write your comment and at the end add an anchor link to your site (anchor link is a clickable link that takes you to your site without the code being visible)
The anchor link should look like this, just replace your site and keyword!
keyword Thats just a start after awhile mix up the links using forum profile backlinks like this site, also use Edu and Gov links,these are very powerful as are contexual links.
Finally try web 2.0 links which are links from places like facebook and twitter, also you can write some articlesand submit to places like Hubpages and Ezines etc.
If you start using these stratergies you should soon find your site rising high for the keywords people are searching for.
Also set up a Google place listing and fully optimize it as it is an easy way to get on page one if you know what your doing
Good luck with your new site
