First you need a physical good or in person service to offer. So much developer worship here and not enough blue collar builder support. As a community I think we need to decide to engage with and especially zap that content more.
After that, local meetups are the way.
I don't do nostr at all for our small business because I don't want address tied to npub by any customers. Margins are small enough that shipping doesn't make much sense anyway.
Now if only I could find a way to stop having schedule conflicts when my local meetup happens.
