Hi,
I am after search engines since a few years , I must say that there are a couple things that I do not understand on your site implementation :
1) why such a long address
www.sellink4less.com/store/customer/home.php , apparently there is no htm or html answer on first level of your address ...try a search with my domain in Google
www.ics-php.com and try a search with yours
www.sellink4less.com [...just type the domain address without http:// ] you will see some difference
2) I peeped into the source code of your homepage output [the long address string] revise the quantity of meta-keywords and set much less and single words separated by a comma.
Have a look in my webpage
http://www.ics-php.com/ev/marketing.htm , I sell a quite different untangible product , but who knows you may get some useful hint.
Every now and then submit some page to Search engines.
You could set your presentations , faqs , tip & tricks etc at least on a upper level and submit those pages to Search Engines
You could then start blogging , I suggest you
http://www.blogger.com/start [...owned by Google] and submit as soon as you have a bit of material ready. Submission takes a couple of months by Google but it's free and works out.
If you think it's useful you can register and sign my Guestbook for free and link and describe your website and with same data you can post in my forums @ ics and create other links to your website.
Hope I gave you some useful tip,
Vittorio
