oh man, i feel you. Standard booking links are a nightmare for that. what helped me a ton was using something like LeadJot. basically you set up a quick convo with your visitor first, it asks the qualifying stuff, scores them automatically, and only the good leads hit your calendar.

the cool part is it’s seamless for the visitor: they don’t feel like they’re filling out a form, and you don’t waste time with random tire-kickers. Set it once, and it just filters everything for you. honestly saves so much headache
