Creative Designer For Pamphlet

I'm looking for a creative designer to do a pamphlet that will be mailed out to 15,000 dance instructors in the U.S. This mailer must look polished and professional. The person I will choose will provide me with 5 unique designs and once we choose the desired design we will get up to 7 revisions. You must know how to design something that will be printed because print shops make you follow their specs or they will delay the mailing. To be considered I need to see examples of your best work. Here are the specs. - The glossy brochure will be cut at 8.5 x 11 - Will be Tri-Fold it. Making 3 panels on each side. - Designer should build it 4/color 2-sided with a full bleed out to 9 x 11.5 with crop marks at 8.5 x11. - Will be a self-mailer so we don't need the envelope. (need to take into consideration mailing address, return address and stamp when designing the cover)
