business planning and business development, whats the difference : I have a great idea for on online social network (sort of) site that will im sure end up a house hold name almost as good as myspace and facebook, but is a completely difference sort of site. I need someone to help me find investors so would I use someone in business planning or business development, whats the difference, I know aobut all the planning but I need to get the investors, though it will not be a high dollar investment like most, it will have a very quick breakeven time and very quickly will be creating revenue and zero debt,
