Your sales copy and site presentation are aweful. First you have no proof of social signals, so setup some likes and retweets about your site. Second, you have no sales copy so how are people suppose to buy if you have no emotion? Also, your pictures are low quality for the services (i.e. the quality is horrible and the image is overused). Instead maybe you might want to make cartoon people happily representing your services like Twitter shirts and a crowd talking about X page (X = example). Also, you might want to start marketing your service benefits. Why buy from you? Do you go out of your way to make sure that each customers psychological and social benefits are appeased or are you just another seller of the same duplicate service?
That is my $0.02 on how you can go about improving your website. Other than that, it is entirely up to you to media buy or ppc buy and test conversions.
