A few thoughts from a GC's perspective..
First, I'd stop competing with the people undercutting you on Facebook. Most of those customers are shopping purely on price, and somebody will always be willing to do it cheaper.
I'd focus on building relationships with smaller and mid-sized GCs instead.
A lot of contractors already have their preferred framing crew, drywall crew, painter, etc. But workloads change, projects get delayed, crews get overloaded, and people move on. If you're consistently visible and stay top of mind, eventually opportunities come up.
Instagram has honestly been surprisingly effective for this. Some of our best subcontractors came from Instagram, not because they were actively selling, but because we kept seeing their work, their professionalism, and their consistency.
I'd also look at lead-generation platforms like RenoAssistance, Houzz, BuildZoom, Angi, Thumbtack, and local builder associations depending on your area. Some are better than others, but they can help bridge gaps while you're rebuilding direct relationships.
One thing I would be careful about though: "we do everything from form to finish" can sometimes make it harder for people to know exactly what to call you for. Sometimes being known as the go-to company for a few specific things creates more opportunities than trying to be everything to everyone.
You've already built a company with 6-10 people before. That's proof that you know how to do it. The challenge now is rebuilding the pipeline, not proving you can perform the work.
