Merlin, don't let them toy with you. Stop what you're doing right now!
No prints, no quote. Otherwise, these fine folks are going to let you do the design, then take your design and let the other guy tear it apart. All you'll get is 'gee, we wanted to hire you but you were so much higher.'
Likewise, they'll learn from your bid just what lies to tell. They told you 'assembly.' The moment they see that costs them money, they'll call it something else.
Don't quote without a design- and don't design for free!
