Very often when working as individuals we get very close to certain details and miss out a big thing that has slipped your mind. You can concentrate so much on essential financials and supply logistics, but overlook other issues like marketing or opening times.

Getting that valuable second opinion on how robust your idea is will put you in a much better position to start and keep going successfully.
