🏠 $500/day installing this simple item
This overlooked side hustle makes one guy $500/day with almost no competition.
I came across a guy on reddit making $500 a day just installing pet doors—and he’s not the only one. After digging deeper, I found a bunch of small websites run by solo installers and small teams, all charging $200–$500 per job with almost no overhead. Some even subcontract out the work, like Pet Door USA, which pays installers up to $100–$250 per hour!

This is one of those low-competition, high-profit businesses that most people never think about. Let’s break down how it works 👇
🚗 The Basics
💰 Charge: $200–$500 per installation (more if you provide the dog door)
⏳ Time per job: 1–2 hours
📅 Jobs per week: 2–8
📈 Earnings: $2,000–$8,000+/month
🚀 How to Start
1️⃣ Get Your Tools 🛠️

Jigsaw, drill, measuring tape, level ($200–$400)
Sealant, weatherproofing materials ($50–$100)
Customers usually provide their own pet doors, but you can upsell & supply them for extra profit.
2️⃣ Practice First 🏡
Install a few doors at home or for friends & family.
Offer discounted first installs for reviews & referrals.
3️⃣ Set Up Bookings 📅
Start simple. You don’t even need a website at first.
Use Calendly or Square Appointments to manage jobs.
Accept payments via Venmo, CashApp, or Stripe.
📢 How to Get Customers

📍 Local Facebook Groups: Post before/after pics, offer a “first-time” discount.
🗣️ Word-of-Mouth: Friends, family, coworkers—ask for referrals
📸 Personal Social Media: Show transformation pics for credibility.
📬 Flyers & Cards: Include before/after pics and your pricing.

🚧 Things to Watch Out For
📝 Measure Twice, Cut Once: A wrong cut = costly mistake.
🌦️ Weatherproofing Matters: Outdoor installs need proper sealing.
🛑 Wall Installs Are Harder: Price these higher if you offer them.

✅ Low Cost, High Profit: Minimal startup, big returns.
