Starting your own business can be a very exciting time, but if you want your business to have any chance of success then there are a few things that you should do first:
Market Research - Is there a need for the product or service that you would be providing? Is it something that people would be interested in?
Legal stuff - Yes legal stuff is boring but it has to be done, especially when it comes to business. Do you have the right insurance? Have you got any copyright laws?
Business Plan - Your actual business plan needs to be a solid one so perhaps seek an appointment with a business advisor before you get started.
