I guess it depends on what kind of help you are looking for. There are a number of books that are available on the subject (at least in the States...), and it pays to check out numerous other coffee shops and coffee shop websites. Otherwise, for more hands-on help, you probably should be looking at a consultant to help you more directly. As another alternative, franchising is also a way to get into the industry, but you'll have more restrictions on what you can and can't do for your franchise.
I guess for starters, that's what I see as your first decision: which of the above routes will you take? If you aren't sure, then you have to start evaluating between a franchise idea or your own idea. After that, then start asking if you want to do all of the leg work, or if a consultant is a better option for you. Start talking to as many people as you can about this, and I'm sure that you'll find plenty who will give you all kinds of advice and help. Cheers!
