Building referral partnerships with other trades
Adjacent trades are some of the best referral sources you've never asked.
List the trades next to yours
Plumbers refer to electricians, roofers refer to siding crews. List three to five adjacent trades whose customers also need what you do.
Build one or two real relationships
A coffee a month with one or two partner owners beats a 20-person 'networking group.' Depth wins.
Send referrals first
Referrals are reciprocal. The shop that sends first builds the lasting partnerships. Asking before giving rarely works.
Take your version of this question further
