I wrote one book with them so I can share a little about the experience.  Note that it was a book, not a video course.<p>- in terms of money, they did keep their promise.  The royalties were 16% which I think is decent in the industry.  They did pay without problem.  Note that if they approached you with the project it&#x27;s because they&#x27;ve done their research and think that there is a significant market for the project.<p>- it takes a <i>lot</i> of time.  Seriously.  I know every single guy who wrote a book will cry about how time consuming it is.  But it is.  I had a full time job and it was difficult to spend another 1 to 2 hours at the end of each day on it.<p>- they had a set schedule for the book.  Basically they will work out a timeline to deliver chap1 after a week, chap2 one week later, etc.  I was not very happy to work like that (note that I worked with them on the timeline to push back a little).  I would have liked having the option to go back to earlier chapters to edit them based on something I mention later on in the book.  Their timeline was also very aggressive.  They used an average of 2 pages&#x2F;day, which is actually really high in real life.<p>- the contact at packt who was working with me was very helpful.  He was always providing feedback and asking me to weigh in.  At the end of the day, I was able to write what I wanted.  They never tried to influence the content (the form sometimes, since they know what looks good in their books and what doesn&#x27;t, which is fair).<p>- I didn&#x27;t like that everything was done in a .doc file. It makes it difficult for me to keep track of versions, etc.  I ended up working with markdown and then having to move everything over to their .doc file at the end of a chapter.<p>Would I write for them again?  At least not for my next project.  I would try another publisher to get a different experience.<p>Good luck.
