8.5" X 11" Catalogue

I already have a 8.5" X 11" Catalogue, it is saved in PDF form and is a total of 12 pages, or 6 pages two sided and that includes cover and back page. THE PROBLEM IS UPLOADING TO CURRENT PRINTER, ONE OF THE LARGEST IN THE USA KEEPS REJECTING, STATING INCORRECT. All I need is someone to correctly save the file 75mb or smaller on these 12 pages so it is correct on there templet. So let me send you the file, save it and upload it correctly to www.gotprint.com
