I do not know about marketing a BBQ team, but, I know a little about building a company and brand. First off, what do you mean by the nest level? Define what the next level is in terms of hard goals. Define how that goal is to be met and identify what you need to reach that level. Will his investment be used for marketing, research, development or equipment? Is he to have an active role (investor) or a passive role (angel) and how will he see his return? Is he buying onto your team or simply helping you build a company. How do you see your product fitting into the market and hows does competition BBQ fit into this, versus catering, how do you intend to develop your market? What will define your product and create separation between your product and the rest of the market? I think a good strong business plan answers these questions and makes pitching to investors a lot more comfortable as you both can see how you will make money.
