Find the company best suited for your design needs. Inform them of the business goals, ideal colors, your clientele, and any other information necessary for the designer to create a logo with all your business' personalities.
Once the logo company design meets with you, they will create several logos for you to choose your favorite. What if you don't like any? No problem! Just revert to the 'DRAW'ing stage and they would be more than happy to start over.
Congratulations! Now that you have a logo, you can start plans on building a website or designing business cards and brochures.
