To start, you should purge everything you think "sales" is. Good sales teams are process and data oriented, talk to customers about solving real problems, and have great long-term relationships with customers. I think your comments about being talkative and being emotional are really just about the phases of sales you'd worth most about which are the introductory meetings and final pricing stages. You can hire plenty of people that can coach you through that.

Whatever culture you are building for you company should be adaptable to your sales org as well, so I'd say you start there. Work the opportunities yourself, start tracking them in a spreadsheet, do write-ups for the company about the wins and loses, and use your founder hustle to get started. It won't be as daunting as you think.
