I did up it to $114/$195 ($6 sq/ft) before sending the quote. That being said, it was for my brother in law who's getting me in the door to do work for his company. They like this logo, opens the door for more work.
So on a basic design like this, what would you be per square foot? I went $6 on this one, it's absurdly simple. They provide the eps file, I cut, weed, and slap it on their drywall. Thats why I went $6.
