Wouldn't usually bring this topic to the forums as I can normally sort out a pricing for most requirements. But this one has got me kinda stumped. Please read below:

"Dan,

Thanks for getting back to me. Our current requirements are for a marketing
brochure. We are looking at a 2.5 x 1.75 for this usage, but we actually
would like to look into using this picture in multiple uses. This is by far
our favorite picture...and we could definitely use it in multiple materials
if possible. The biggest size we would ever use is 8.5x5.5

Thanks Dan"
