"We offer... consulting services at rates that are much less than you might find from other US based software firms"
You'll notice that nowhere do I say we're prepared to compete against teams of highschool kids in Bangladesh on price.
I still like to think I'm competing on quality rather than price. The fact that I bill less for my time when I've got sand between my toes is frankly a bit of a gimmick. Some clients see it as a positive that they're contributing to my suntan.
