I think you need to look around. Companies spend a small fortune for their logos. Why? Recognition. If I showed you some images, you would immediately associate them with the companies they represent. Not only that, but you would also have an instant impression of that brand.

Would you make one more new sale with a logo? I can't say. I will say that if a customer/client likes your product, they will associate that with your logo. They see the logo again and they will most likely buy from you again because they are familiar with your company. Much easier for the human mind to recognize an unique image rather than only a name.
