You know what the standard RFP is... a powerpoint presentation loaded with product mixes, metrics, and creative examples sandwiched in between a logo title slide and a thank you slide. This is pretty standard process for media sales planners.
What would make your RFP standout? For a Cap'n Crunch RFP at Tremor Video we decided to redesign the entire cereal box... we opened up the cereal made a small opening, inserted a USB drive loaded with the sales deck (as if it were the prize at the bottom of the cereal), we resealed the bag of cereal, glued the box shut and sent it off to the agency as if it were bought straight off the shelf.
The agency loved it and said they had never seen anything like it before.
