Tri-Fold Brochure ReDesign

I have a tri-fold brochure for my web services company that was designed earlier this year in .psd format. I am looking for a professional print designer that has worked with U.S. clients on print projects and understands how to format a tri-fold (8.5"x11") to the exact requirements for printing, folding, etc. I have a logo and will be using the general content from my old brochure, but I'm looking for a more professional, more corporate look and feel so I look as though I'm a larger / more established firm to complete with other larger companies. I can get you whatever stock photos you need from iStockPhoto. I believe the standard format for a brochure is either using Adobe Illustrator (.ai) or Adobe InDesign (.indd). I think .psd and Quark is also a possibility. The final receivables should be completed approved source files for the brochure (.ai or .indd format) and a PDF proof that I can use to take to my printer to print the brochure (SEE ATTACHED FILE FOR DIMENSIONS & SPECS) If this goes well, I will be doing more print design projects in the future (double gate folding 8.5"x14", 11"x17" brochures, folders, as well as outsource print jobs for my web design clients). Bidders ... please have a track record for positive feedback on GAF and please provide examples of work.
