It should tell "WHAT YOU DO"...
Should be "EASY TO REMEMBER"... so they can recall it six months after they hear the name...
and in a time of the internet (and people who learn to spell from their friend's "texting language") ... "MUST BE EASY TO SPELL"!
If they can't connect the name to your services... or remember and spell the business name... it really doesn't matter what you choose.
As an example... the name I chose is "hotrodpaint.biz". Simple... easy to remember... and to spell.
