Packaging/Label Artwork Design

We're looking for packaging artwork for our product polybags. Our products are toy related (building blocks, similar to LEGO bricks). We would like the center area of the package to remain unprinted in order to allow for the customer to see the item(s) inside. We've attached an example of a polybag lego offers that we like. The second packaging example we attached is something we like due to its simplicity and clean look. Our logo is attached as well. Packaging should be in 5" H x 7" W clear poly bag with serrated edges on top and bottom. I'd like to incorporate some sort of lego look alike brick into the packaging artwork. Our colors are bright orange, as seen in 5x7 Polybag Artwork attachment and red.
