This isn't a specific answer to your question, but it is interesting to note that there are many services who promise to submit sites to search engines. Some of them promise to submit to several dozen search engines.
The truth is most of those search engines are almost of no benefit. There are only 3 search engines that really matter. There are 4 if you include Ask.com which is slowly making some progress.
Here is a link to a post I made a few months ago. Things haven't changed all that much since then. Google is still the big important one.
The most important thing is that at that time, the top 3 search engines accounted for 94.5% of all searches made.
Google breaks 60% search market share
The major search engines like to find you themselves. They offer submission services but don't guarantee that you will be including after submitting.
Right now when it comes to search engines. All that matter are: GOOGLE, Yahoo, MSN and Ask.com.
