I'm trying to build a LaTeX document class, so that documents for my association can be easily produced using LaTeX. The problem is, the documents use a very specific branding that includes a logo and page headers using the Gill Sans font.
As you are likely aware, using a custom font in LaTeX is a world of pain (as expressed in various questions here and on superuser).
I have stumbled upon Gillius ADF, an open font that is inspired on Gill Sans. However, it is noticeably different, and not really an option for me.
Many suggestions come down to using either LuaTeX or XeTeX. This is far from ideal; sure, I would be able to switch, but the idea is that this document class should be usable for people who have only limited experience with LaTeX.
An alternative that came to mind was to somehow generate PDF files of the page headers on the fly, by replacing texts in existing included PDF files.
I'm looking for any and all suggestions; what is a robust and user-friendly way to include a non-standard font in a LaTeX document class?
