Tip: Register your own domain
If you want to set up a business and not a personal homepage, do register a domain. There is no sense at all to get a web address that looks like this:
http://www.somehoster.com/your-business-name
or
http://www.your-business-name.somehoster.com
Why?

Ad 1: Nobody will ever remember it

Ad 2: It looks and feels like a very small and new business

Ad 3: It makes you look like you don't even want to invest 15$ a year for your own domain name

Ad 4: If you ever choose to have a different hosting company, you have to change your whole web address (if you register a domain name, it is transparent for your visitors)

Ad 5: You might run out of space on your business card
