How do you keep yourself going before the money starts rolling in? What if the money DOESN'T start rolling in? The following case studies tell stories of enterprise success - and failure. THE SMELL OF SUCCESS: S'Amuser is a bold experiment in retailing - a business in Glastonbury offering customers the chance to blend their own perfumes. But this high street perfume bar is only the beginning of the founders' business concept. Their aim is to launch franchises all over the country. THE CRISP MAKER: Fed up of being pushed to cut his prices by the supermarket buyers, Will Chase thought of something else to do with his spuds - make them into crisps: hand-cooked artisan crisps. It was a big investment and a huge risk, but it paid off. Tyrrells crisps are Britain's big snack food success story of recent years. BONE BUSINESS: Ayshe is an osteopath - she cures people who have pains in their backs without using drugs or surgery. Most osteopaths work in clinics - but Ayshe has set up her own business called Backbone. Word of mouth is her main form of promotion. The One That Failed: Jonny had a bright idea for a business - finding venues for companies that wanted to hold events. But cash flow problems meant he had to give up.
