It's tough these days to name a business. You want your business to stand out, you want a URL that is memorable (if you can find one!) and you need a name that your competitors haven't already taken.
All very true.
Sadly, many business owners think they're being clever when they opt to misspell a word — like when someone substitute a K for a C or Q, Or an F for a Ph.
So unless that's what you're going for — keep trying.
