When getting a logo made you need to be educated in what a logo can do for your business' image.
Greece was the first country to use logos; it had a symbol of a snake covering a staff which was a sign of the Greek god Hermes. This symbol later represented Asklepios, the Greco-Roman god of medicine, and the symbol is still used by doctors. Greek and Romans had their rulers' faces were even engraved on their coins. Later, people belonging to different professions took up various symbols to represent their trades. They started by using their initials as logos. Later it was became a trademark that represented the values that were dear to them and lent credibility to their trade. Modern logos have the same motivation. They are used to represent your a particular trade, to promote a company's image and giving brand recognition.
Logos represent a name, symbol or trademark. You can put a logo almost anywhere including: business cards, letterhead, envelopes, statements, invoices, hats, pens, watches, vehicles, etc. Since it plays a vital role in representing your company, you should be very careful when it comes to choosing a logo.
Make sure your company's logo and name are registered as trademarks. If you do not your money may go to waste. Registration gives you rights to that logo and no one else can use it without compensating you for its use. You will be required to file a Federal Registration of your trademark which can be a word, name, symbol, device, or an amalgamation of these elements to identify the business.
