idk if you want a yellow page, craigslist, or eBay(this type of site have web effects meaning if you don't know probably don't exist), and probably what I THINK YOU SEARCH (at least in Argentina) happens in fb marketplace and parts exchange groups(idk to much people using fb outside of this) probably search a group of hobby who focus on that, communities selling "garbage electronics for cheap" and "hacking space like" who can help you sometimes in exchange for money or share passion, i wish this be helpful if not sorry.
