Proprietary search stack: cracking owner contact info on low-digital-footprint SMBs?

After about a year of reviewing on-market deals for B2B services, light manufacturing and distribution, I'm shifting real effort into proprietary search and running into a data problem I'd love the community's input on.
I'm running two parallel sourcing workflows: Apollo searches using SIC codes and B2B filters, and Google Maps extractions along specific industrial corridors. Once I have a target list from either source, I run a waterfall to get to the owner. Apollo first, then CA SOS for the legal entity and registered agent, then LinkedIn and the company website.
The issue is that Apollo and most tools in this category rely heavily on LinkedIn, and a large share of SMBs I'm targeting have zero LinkedIn presence. I've also noticed that the corridor approach surfaces many real targets that never show up in Apollo's database at all.
Two questions for the community:
1.) For those of you targeting similar low-digital-footprint SMBs, what actually works best for surfacing direct owner contact info?
2.) Has anyone had success using Upwork VAs for this kind of contact enrichment? Curious what the workflow, rate, and quality looks like in practice.
Appreciate any input!
