Great question and I'm in the same position as you! 100% healthcare and a pinch of local business. Real estate people are conservative and don't like to adapt new technology. Coaches are great but price-sensitive. E-commerce is good but you're competing with stuff like Shopify. Local businesses are great though it's sorta fragmented, you'll spend a lot of time on sales. Healthcare is a great option though! Doctors, clinics, therapists, etc.. need people but they're tech-savvy. They want sign-up forms, follow-up systems, etc.. So I'd say like 70% healthcare 30% local businesses. I'm a webdev studying my market and I built this tool using Nebula.gg (which creates and auto deploys websites) and the Foursquare API (to find businesses in my area without websites.. I only used Foursquare to test though bec its free, You should use the Google Places API). Build yourself a tool like this and you're gold
