Once you have a new website or you have made significant changes to an existing site, you want Google and Big to pick up the changes right away. They will find your site eventually, but there are a couple of things you can do to expedite the process.

1. Get an established site to link to you.
2. Submit the site to search engines the quick way:
   1. To Google http://www.google.com/webmasters/tools/submit-url
   2. To Bing http://www.bing.com/toolbox/submit-site-url

Or set up your site with Google webmaster tools from Google (http://www.google.com/webmasters/tools) and Bing (http://www.bing.com/toolbox/webmaster). It takes a little longer but over time the accounts will set you up with more info that will help your search engine ranking in the future.
