As this project appears to be fairly unknown in the fediverse still, I’d like to use this opportunity to advertise Flohmarkt. This Fediverse equivalent of Facebook Marketplace already has some instances up and running - see here: https://codeberg.org/flohmarkt/flohmarkt/wiki/flohmarkt-instances
I just set up a Slovenian instance, flohmarkt.gregtech.eu
Edit: which range should I use for it, which one do you recommend?
