Don't try go it alone. You're the expert at what you know, get others to help you with the skills required that you are less familiar with. This includes things like advice on packaging for your product or sourcing a packaging supplier, finding a printing service provider, website hosting, logo design, delivery services, accounting services and so on. It can save you a lot of time as you don't have to do all the research. You get referred to tried and tested service providers and you will receive great advice from people that had to figure things out themselves.
