Photo collage high resolution

I need a photo collage for printing? in 9000x6000px? landscape. I will provide a set of upto 100 4000x3000px photos. The collage will have a central group photo in? large, and others will be arranged as ornament or open to proffesional suggestions. It is desired to have some graphics that will compliment the photography. Filters, borders and such as/when needed but not too much. ## Deliverables The output will be in PSD, where each photo/art is on separate layer. Also, there should be a flatten JPG, or TIFF picture in exactly 20"x30" size. * * *This broadcast message was sent to all bidders on Sunday Jan 3, 2010 8:22:34 PM: If you haven't yet, please provide a sample/URL of your collage.
