Medicare Flyer

I need to create a Medicare Dinner flyer like the one I have attached. A couple of changes I need to make to this original, include removing the stamp box and moving the Date/Times/Location to the upper far left (replacing the "You are invited Free Educational Medicare Class! Dinner is on me!) on the backside. Also on the backside, move the RSVP info to the left side as well, so that there is no writing under where the address goes. I've attached the PDF documents that I used in this one.
