Great idea. Just one little tip: I would not use the combination 'Instant and PDF' in your communication. Instant PDF is a well known product by Enfocus. It's basically a check-app for Print-optimized PDF files. As such it's a world-wide standard designers are forced to use. Create PDF, run it through Instant PDF, if approved it will attach a flightcheck report to said PDF and newspapers, magazines, printers can process the file. The flightcheck searches for common mistakes (non-embedded fonts, rgb colors, low res photo's, etc). Recently the Instant PDF name got absorbed by Connect but the brand Instant PDF is quite powerfull really).
