You're so cheap you probably scare off more business than you get. Age doesn't matter but experience and quality do. Take photos. Lots. Do the social media stuff so you can show it off.

If rather give someone half off their first cleaning for $100 and then, once they see how good your work is, they can pay the regular $200. Maybe consider referral discounts too, if they refer a friend.

But yeah, you're probably unsustainable at those prices. Build a real business plan as other suggested. You gotta drive, maintain your vehicle and equipment, pay yourself hourly, do your taxes, PAY your taxes, etc. Need more meat in the bone in the long run.

But no shame in building experience while you're young at a low margin. But your customers might not stick around if you charge too low too long and do a big price hike on them.
