Just for the record, I just downloaded Adobe Acrobat, and org->html->acrobat seems to be a viable workflow, and not as expensive as Prince. 

However, Acrobat, as far as I'm concerned, doesn't provide any way to automate the process - you have to open it and edit it manually in order to polish the typography and add additional graphical elements, but seems to be a great alternative.

Cheers,

Will this work for you?
