The target market that will pay for PDF generation is probably not developers.

A competent developer can generate PDF's with the mentioned libraries rather quickly. We deal with a lot of PDF generation where I work, and it is not something that enters our minds to outsource because it's pretty fast and easy to do. For us, the generated PDF's do not need great design or layout, they just need the info in a printable format.

That said, you may find a better audience with less tech savvy users that have a lot of reporting needs. I can't really think of a target audience off the top of my head. Good luck to you.

I disagree, If we are dealing with simple invoices and stuff. Once you start dealing with reports containing charts, it all goes haywire
