How to Negotiate in a Brand Partnership?

I've been thinking about this as a course, and i think it would be really powerful that also then goes into like, live zoom negotiations. Regulation in our industry is challenging right now. If we had a course, wer i had to negotiate and you were the brand manager, you i just thnk that'd be very difficult for me. I'd much rather play the role of ser the brand. But id be fun, and it's something that i should learn.
