You need a better product. A flashy sign out front or a cool header on a website doesn't mean anything if what you sell sucks.
People don't by iPads because of Apple's logo. Craigslist doesn't even have a logo. People don't walk into Starbucks because a mermaid beckons and JCPenney can use all the lowercase letters it wants but people still prefer Amazon. Borders didn't fold because it never found the right look.
Spend your time doing something awesome instead of drawing.
