Don't ask what services I offer.
This is advertising and I'm an ad guy. I would put on a bear suit and hand-out balloons if I thought that would do your brand any good. So don't ask me if I do websites or billboards or brochures – of course I do.
Don't tell me the dude at Local 7 News is putting together your TV spot – all that's going to do is waste your money and make me lose more hair. If there's something you need, and feel inhibited by costs, let me know before hiring some hack to schlock something together. We'll find a solution.
If there's something your brand needs to do that I can't, I'll find someone who does it and does it well. I'll look into who's out there, evaluate their various attributes and fees. Then I'll make you a recommendation and charge you for it. It's simple. Between you and me, we can make anything happen.
