For good business name ideas simply Google Search your chosen field or product area in the USA, Canada, or Australia, that will supply you with 5000 tried names ideas for starters. Look for dealership lists. Your gut feelings do matter - you will have more personal confidence and name-pride if your sub-sync values that name more than others.
Your chosen name does not matter too much INITIALLY to buyers or others, nor will they really understand or care why you prefer lets say Blue Sky, over Blue Ocean, Blue Oddyssy or Blue Lagoon. The word blue sky can stand out, look drab, look odd or impressive, can look great or look crap, so you need to study typography and word association games. In the USA they add a company slogan to gain more credence or street cred. Avis, We are number 2 springs to mind.
Were names really matter is in banking, insurance and property. In these fields you need to suggest stability and confidence. I love brilliant trading names but not Wonga, Ogg, Moggie, Egg or O2.
