Claudia,

Take a look at www.Amyuni.com and their PDF converter product. You can download a full working demo (with a watermark across it) and write up a quick "proof of concept" program to show the tightwads!

The product has a near flat learning curve and doesn't make a mess of your system. It's the kind of thing you could knock off in an hour or two. God bless the demo....
