Warning! Newbies, if you are going to send a 'design' to this guy, make sure that it has a watermark (a very imposing one) and/or the file or layout is not at final resolution.
You should protect your work, what could stop him from showing the design to another designer that's cheaper -- or stealing the idea himself.
Understand that in the design world, I barely ever give mockups like this (or my company for that matter) in a paying environment. I will show you simple, rough layout ideas; if they choose to move forward, then contracts are leveled out.
It should not be this way -- you're essentially doing work and maybe not getting paid for it from someone you don't even know. Why should you have to wait around why he decides, after you spent all that talent and time?
This is obviously Steve's first time working with designers (if ever working with a professional firm); he would not have asked for submitted designs. This is not a bid for the Smithsonian, or the 9/11 Monument -- understand he can gauge your 'talents' by looking at previous creations. He should then pick that firm/designer based on their work -- you guys write up a contract based on an agreement that you will be billing for your mockup and initial designs. If he does not like them, you own the designs, and he either pays you for your time spent, or you can both agree to disregard the money. The point is to keep your work yours.
How many people will he show it too? How many will he send emails out who can view or copy it?
Don't spend 20 hours on a layout that could be copied, and you could never see recognition for it.
