A coupon mailer that fits in a #10 envelope

I need an advertisement designed in a .pdf file that will fit in a number 10 envelope with a letter and other advertisments.? I will attach one that is currently going out and need something similar to it.? I will provide the logos, but we'll probably need to email back and forth to get the approval. ## Deliverables I'll have to email winning bidder, what I have since I can't upload file here.
