please review my app - html to pdf API
latortuga: We used an html->pdf conversion service (I believe it was http://www.htm2pdf.co.uk/ but I'm not positive) for awhile to do billing and our biggest problem was that it went down all the time. We ended up purchasing a (pretty cheap) license to a Java library that does pdf generation for us and is pretty easy to use. This is definitely a service that people will pay money to use - best of luck to you!
