I am pitching an idea to a developer on sunday. If he likes my idea/what I have to offer and he wants to enter into a partnership, how should I proceed? Is it unprofessional to ask him to sign an NDA before I pitch? Should I bring any contracts with me? He lives ~45 minutes away. Is meeting once a week often enough? What other concerns should I have? What aspects of the business/business relationship should be discussed? He is an unemployed 32 year old, married, college, ex-military. I am 22 year old fashion student/aspiring entrepreneur.
