From my copy writing experience, I can say your website lacks certain psychological tweaks that will force your visitors to buy. You have not highlighted the features and benefits of your product in a convincing manner. You need to add at least a few testimonials on the index page besides the separate page you have created for it. Moreover some other NLP tactics can increase your conversions.
Moreover, for promotional purpose, I would suggest you should set up a blog on your domain immediately where you should write a post at least every day for One month and then you may write two or three posts a week inserting anchor texts leading to your website.
Get the rss feeds of your posts every week and submit them to:
http://www.feedagg.com
http://www.feedage.com
http://feedfury.com
http://www.syndic8.com
http://www.rss2.com
2- Set a target to write 5 articles a week and submit them to the following article directories:
http://www.articalz.com
http://www.ezinearticles.com
http://www.goarticles.com
http://www.ideamarketers.com
http://www.articlealley.com
3- Make powerpoint presentations of your articles and then go to
http://www.slideshare.com and submit your presentation linking back to your website. Make a thorough keyword research and put those keywords in your Title. This will rank your website very high in search engines. Please don't forget to submit your slides to social bookmarking websites using
http://www.onlywire.com
4- Use the same articles, slightly change your titles and submit them as a press release with a link of your website of course at least twice a week. You can submit your press releases to the following websites:
http://www.prlog.org
http://www.pressbox.co.uk
http://www.i-newswire.com
5- Set up a squido lens. Change the title of your lens and also write a unique introductory paragraph of your lens then add two or three same articles in the text modules of squidoo. Then submit your lens to social bookmarking sites. Also submit your lens rss feed to the above rss directories. Moreover write 3-4 new articles and submit them to the above article directories linking back to your squidoo lens. Now one very important help you will get from squidoo is that you will get those long tail keywords that bring people to your squidoo lens. You can see these keywords when you check your squidoo lens stats inside your squidoo account. Now you have TWO options:
i- You may write more articles on the basis of those keywords
ii- Write keyword rich blog posts targeting those keywords
Do whatever you like.
6- Make short videos using powerpoint and windows movie maker and submit them to:
http://www.youtube.com
http://www.tubemogul.com
http://videos.google.com

7- Use classified sites like craigslist,backpage,gumtree,kijiji,uslisted etc for more exposure.
Remember, internet marketing is a fun if you manage your time and divide your marketing time according to your own needs. You should never stop promoting your biz. Every new post with your website link you add a day will surely bring traffic to your website and traffic means chances of getting sales. I hope this will help you do your job well.
