We can't find an easy url to match our company name

What should we call our business? We had agreed on Beltway since we were selling customs belts from around the world. When tried to register beltway.com, we found it was already taken by a company with an unrelated name.

Other urls such as The-Belt-Way.com were available but nobody liked them. When we contacted the site owner for beltway.com, they wanted $100K for it.

Do we change the name of the business because we can’t get an obvious url for it? Should be choose the domain name first? Do we have to have “.com” ending?
