Is not an easy task...but it can be done.

IMO the easiest way is to create an evento on Meetup and do a Bitcoin presentation for beginners in your city. If you don't want to pay the Meetup subscription it will be hard to find new people...If you go to Telegram groups you could find some local bitcoiners.
