Don't bother with a service like that.
Think about what the job of a search engine is - it's to scour the web to provide it's users the most complete information about the topic you're searching about. If everyone has to submit their sites to search engines, then the search engines really aren't doing their jobs.
So those submission services are more scam than anything.
Besides, there are only about 5 search engines you need to concern yourself with: Google, Yahoo!, MSN, Ask, and whoever is in fifth place. That makes up 99% of all the search traffic.
The other 999,995 "search engines" probably won't net you any traffic at all. There are a few exceptions, but not many (out of that million they advertise).
What to do instead? Get yourself a few inbound links to get your site spidered. Submit your site to landscaping-directory.com. It's a site I run and in it's current format won't get you much traffic, but it will get the spider bots over to your site.
Many times associations will have sites with links to member sites - get yourself listed on those. Get 5-10 nice inbound links and you'll start seeing some improvement.*
You might also consider getting your own domain and putting your website there - more elikely to get traffic, and you'll look more "legit".
Hope that helps. Feel free to ask any more questions you might have.
*Conditional on a lot of things, too complex for this time of day for me.
