Ah the age old "get me to the top of Google" request
I didn't know you worked for them, the have some cool cars
Its a combination of site design, popularity, and money. The quickest and easiest way is to advertise using Google Adwords, it'll cost a bit (its upto you how much you spend though), but in the end you can scale back your advertising when your site becomes more popular.
I specialised in this many years back. I spent a lot of time on our site when it was first released, "Envy" in Google now comes up 4th out of 23m, which for a generic word is fantastic & we come almost top for everything we sell, which is where you want to be!
