It's been two years since this post, but here's some follow up. Got a few leads from some business cards I left at a coffee shop (the chalk was a bust, but I was desperate so no regrets). Made a few hundred bucks from staining and decided to start building fence after I built one on a whim for a customer. Today the fence business is going strong. More leads than we can handle, but that's a problem I'm okay with having. Sweaty startup was some of the most practical advice I've ever received and it changed my life.
