150 unique visits is a good start but you definitely could do better by ranking higher for keywords that are searched for more frequently. "Mobile Website Business" only gets about ~46 local monthly searches. There are other keywords out there in the mobile website business that are have more than 1900 local monthly searches. Such as "mobile websites" I would concentrate on creating content around those keywords instead. Google Keyword Tool can provide a lot of the keywords I'm talking about. The overall look of your site is good but not really optimized for selling. The font is a little small and the "Get Started" button design is a little weak. It would be interesting if you could test different sized "Get Started" buttons. Also test if getting rid of that extra step between "Get Started" and "Order Now" would help conversions. You could also use Adwords/PPC since your site is already converting, but that's a whole different topic.
