Those will at least give them a "heads up" about your site... but if you want to get shown on the first page of search results you'll have to...

1. Have relevant content (articles, information, etc.)
2. Have links to your site (not as critical as some make it sound, but it helps)
3. Learn

Check out a site like problogger.net for tips / techniques related to blogging that can be applied (somewhat) to "traditional" sites.

Also, after checking out your site, I'm still confused on what it is you actually do. I would suggest expanding the information... give examples, case studies, etc... The benefit is two-fold... 1. it gives search engines something to use to figure out what your site is about and 2. Once people stumble across it, they'll be able to figure out what you offer. If they can't, they'll hit the back button and try somebody else.
