I found the "onboard" and tutorial for the forum to be very helpful in understanding the flow of the site. I'd like to create something similar for my site but have no idea what to call it or how to refer to it so that I can create the project to outsource. What is the trade name for those types of walkthrough tutorials and how can I find a low cost outsourcing option to tackle such a project?
The discipline is called user onboarding optimisation.
A simple Google search for https://www.google.com/search?q=user+onboarding or https://www.google.com/search?q=app+onboarding
should get you started on the right path
