Any public labeled dataset of (customer question → seasoned sales response)?

I’m looking for a dataset where the input is a customer question/objection (ideally with some product + context), and the label is the response a seasoned salesperson would give to sell that product.

Not customer support, not generic persuasion—specifically sales responses grounded in product facts, with a “move the deal forward” intent.

Bonus if it includes metadata like product category, persona, stage (discovery/close), and outcomes (conversion, next step, etc.).

Does anything like this exist publicly? If not, what’s the closest proxy people use (call transcripts, negotiation corpora, synthetic generation, etc.)?
