Hi Garden...welcome to the forum...
before you commit any time, effort or money to your proposed venture contact your local Business Link Office, they will assign a Business Advisor to you and he/she will help you identify the potential of your business and aid you in compiling a Business Plan - if and where necessary your Advisor will also help you to obtain specialist advice and help you access any available grants that you maybe eligible for. You can find the contact details of your nearest Business Link office by visiting the national website (just google for it). Don't trust to luck or guesswork, get proper advice based on fact not fiction and you are more likely to succeed...good luck.
