Geographical areas: London / notting hill / chelsea / bayswater/ east london
Data to include: market size, trends, consumer behaviour , consumer needs
Extra notes: I am drafting a business plan for a concept store in London in the areas mentioned. The store would be a fun / quirky store selling only fair-trade and ethically sourced / produced products.
