okay, here is the deal, your on-page SEO is out of wack, the urls are not seo, the title tag is duplicate on all pages, the keywords are not in the correct order, etc. SO FIX YOUR SEO!
Now, you also have a trust issue, some how you have to look credible and instill trust in your visitors. DO THIS BY GETTING THE BBB ONLINE SEAL OR MOVE YOUR SSL SEAL CLOSER TO THE TOP OF THE PAGE SO IT IS VISIBLE.
Moreover, study your order process/page and see if you can reduce steps in the process.
I would also recommend that you sign up with google/analytis and create your ecommerce funnel so that you see exactly where the customer stopped in the ordering process.
SEM, do SEM but do it SMART, don't go and use google default recommendation, start slow and little but always have 300 or more keyword variations, including misspells.
Affiliates, get involved, talk to deal sites, like slickdeals, etc... and see if they can help you, usually you pay per sale but you can figure that out with them.
Now, go and add your products on google:

Join your local chamber of commerce and network.
Hire someone to a do a basic SWOT analysis for your site.
So, that is all for now, I am tired and will answer more questions if you wish. If this information is somewhat helpfull, you can buy me a case of beer here:
