Billy the Exterminator was on A&E; show was about a family pest control company in Louisiana. Lots of episodes on Youtube.
And with respect to feral cats - many feral cat non-profits will pick up trapped cats and provide free spay, neuter, and vaccinations. The cats will be released back to the general area where they were trapped.
Glad to help.
And figure that you will also encounter live animals like feral cats. Think about reaching out to local organizations that provide fix/neuter services for feral animals or animals in general.
If you offering safe trapping you need someone to hand off the trapped critter. Naturally, if it is raccoons or possums, they can generally be released into local wildlife areas. Check with the municipality.
Don't know if you've watched the show "Billy the Exterminator"; if you haven't, I think it would be valuable. You need to brand yourself.
Contact the local Association of Realtors and see if you can buy a small advertisement on their web newsletters. Nothing kills a sale like a rotting carcass in the crawl space.
Other potential clients would include management companies, financial institutions, and educational institutions/local school system. Lots of portable classrooms have issues with critters.
And decide on a clever company name that people can remember.
Ebay - $5.30 Biden toilet paper. Free shipping.
On Etsy, Bowl Face Liar (seller name) has many toilet/lid decals for $14.99. Shiftee, Fancy Nancy, Creepy Joe Biden, Hilldag, Bernie etc.
Make her shit time memorable.
Get a rope.
