I work with a FOSS project that needs better documentation. We have some written stuff but want to add video guides and some more written stuff as well. There's also some desire to re-organize our existing documentation using some system like ReadTheDocs etc. Our devs are good devs, not good documentarians. We have money.

I know we could just go on upwork and find somebody to make this, but I'm curious if there's a company or organization out there that specializes in making documentation for FOSS projects? One we could pay to have this done?

Edit: Not going to name the FOSS project, don't want this post to look promotional. I am just trying to see if the service we're looking for exists.
