OT This article prompts a thought: I want to sell a price study we did as a startup (in Germany) to businesses. Study is in PDF and price is around $300. Primary targets would be businesses. Any suggestions on where to sell? Probably best if the website offers also invoice payment and knows how to sell to businesses? Some kind of personalization of the PDF (Buyer name etc.) would be nice for 'copy protection'. Not sure about mobile? DIY? Thanks :-)
