Built an AI quoting tool for contractors — my neighbor was losing jobs because quotes took too long My neighbor runs a small moving company. Good guy, works hard. He kept losing jobs because by the time he emailed a quote, the customer had already booked someone else. He'd spend 20-30 minutes writing each estimate — pricing research, word it professionally, format it, send it. By the time it went out, it was too late. So I built QuickQuote AI.
