Create your own Free Collaboration Network
If you can't find an FCN near you or that suits your needs it is very easy to create one yourself.
It can be as simple as a phonechat group (with signal, telegram or whatsapp). Create a message group and invite people you know to it. You can also create a Facebook or Slack group and start offering and requesting goods and services that you can.
Unlike other more complicated mutual aid systems or coops, FCNs usually don't require any legal set-up, funding or paperwork - just a group of people helping each other out.
