Need some input on door clings

[Brian]

I have a mall tenant that wants two side window clings done. He needs 40 of them 12"x12". I was planning on printing in reverse on clear and laminating that with plain white vinyl. I will print the face side with gray back vinyl and laminate that side. Then mount the two together. With the clear vinyl going on the glass and the gray back being the face side. Any idea what to charge for these. They will be labor intensive. My proof does look great though.

Any help would be awsome.

Thanks Brian
