Your rank is based on keywords people search for. Try and use the products you have and keyword them through google, so when someone types in that product you can start competing in the rankings, the more relevant you are to the product the better that rank. For instance: sound services gets 9,900 global searches per month and 1,600 local searches. As you already have Sound services in your URL then you are primarily relevant to this search. It's just a case of backlinking your URL all over the net and play the google waiting game.
