Ok, so just as a few people stated, for me the big STOP was your website design. Seriously. I don't want to sound rude at all, but you asked for it.
We are in 2011. Check out the wonderful sites out there. People are emotional, they react to what they see and are mostly influenced by colors and graphics than by rational specs and pricing.
When I saw your web design, I was automatically telling myself: this was made by a non-IT/computer specialist, and probably a 1-man business. It doesn't look professional at all: who would host his website with a host that is not good with websites?
I am not saying you need a 3d rotative flash & sound bleeping cutting-edge site, but just something people will tell it was professionally made.
Then, once people will want to look at your page because they don't run away from the landing page, they will start to lurk around and see that you offer a good service. But the plans comes second if not third in terms of importance.
Hope this helps
EDIT: Marketing is not rational!
