I`d suggest not getting too bogged down in worrying about finance at this point. Much better would be to have a detailed business plan, factoring in all the things you`d need to get started, then all you`d need to grow. What would you mean by "growth," and can you segment that growth into phase 1, phase 2, and phase 3.
When you have that organized, you`ll probably find financing more easily that if you worry about how to find capital before you have all the details.
Or....do you have all those details already?
Also---and I just thought of this---have you contacted this member, "LaCremaCoffee?" He`s very into custom blends, and I`ll bet would have lots of thoughts about opening a coffee shop..!
