Hello @reko!!
We are just starting but our mission is to spread steemit community in Spain and help spanishtemians to grow up with steemauto trail.
We use currently #upfundme tag to buy a Drone and make #promo-steem / #promo-spain vídeos.
Idea: Sharing resources is really cool!
We'll be recording #introducemyself videos for new members who ask for this service.
You can use your own resources or get help from steemians.
Writing about amazing projects(like yours) seen here in Steemit is another cool way that i think could help to promote Steemit blockchain.

My best regards! 👍👍👍
