Marketing hardwood deck services — what's working for you?

I'm trying to grow the hardwood side of my deck building business. Currently about 30% of my projects are tropical hardwood, and I want to get that closer to 60-70% because the margins are better.

What marketing channels are working for other hardwood-focused builders? I've been doing:

• Before/after photos on Instagram
• Google Business profile optimized for "Ipe deck builder [my city]"
• Word of mouth/referrals

Anything else that's moving the needle for you?
