Lead Gen for House Cleaning in Rural Ohio - Cold Outreach Scripts That Work?

I've been grinding away at lead generation for my house cleaning side hustle, and out here in rural Ohio the big box stores aren't helping much with the foot traffic. Decided to try cold outreach last month, hitting up local Facebook groups and emailing real estate agents about post-move cleans. Landed two solid $200 gigs from agents who needed quick turnarounds before showings, but most responses are crickets or 'we have our guy.' Anyone got scripts or tweaks that actually convert better for residential deep cleans? Thinking of adding door hangers next, but worried about the backroads vibe. TBH, it's frustrating when Angi leads cost $50 a pop and half ghost you.

What kinda response rate you getting on those emails to agents?
