I have noticed that some of the highest quality and conscientious designers are the ones that do it for the love of it and the game and the Sims community. Those types of designers almost always offer their work for free to the Sims public.

There are a lot of wonderful free custom content sites out there. Those I am listing here are ones that I trust and ones that I actually use.  If you have a recommendation of a site you believe should be on here, message me and I will check it out.
