By far the BEST approach to sending us your project, from virtually ANY computer using almost ANY software is to send us your files in the Adobe Acrobat PDF format.   One advantage of using PDF files is that they allow you to see how your file will look when printed.  Another is that they'll look, AND PRINT, the same way once they reach us if you create a high quality PDF with the fonts embedded.

  The full Adobe Acrobat program is VERY expensive.  Thankfully, there are FREE options.

 Primo PDF is a totally FREE program for high quality PDF creation, comprising a user-friendly interface that enables printing to PDF from virtually any Windows application.  This tool is completely free, not just a trial version, and no user registration is required.  Simply download it, install it, and when your project is ready to send, go to your print option and you'll find a new PDF "printer" has been installed.  Obviously this is not a real, physical, printer but it IS the driver to write the PDF file that you will upload to us.

 Pdf 995 is another FREE program that makes it easy to create professional-quality documents in the popular PDF file format. Its easy-to-use interface helps you to create PDF files by simply selecting the "print" command from any application.
