If you own your own company, there may have been a time when you had to do everything yourself, maybe when you first started up. This could be everything from the marketing to the accounts along with the technical side of the company. As the company grew you may have been in a position where you needed to take someone else on. This can be extremely daunting the first time round as you are having to let someone else in to your business and therefore you need to be able to trust them.
Ideally you may want to find someone that you already know or have worked with before but this may not be practical. When you come to chose what type of person to take on you need to have a clear idea of what responsibilities you will be giving them. This will help you look for specific skills and qualifications. I would always recommend either giving someone a trial run or an initial short term contract so either party can part ways should it not be working out.
