If you are starting a business and need a logo as well as stationery and a website, don't rush into getting anything mass printed until you know that the web address you want is available. This is something we can help you sort out.
Think about who your target audience is. We realise you weren't born yesterday, but this has implications if we are talking about websites. Your viewers may include people who are using a smaller computer screen and will determine how big your site will need to be visually.
Think about what you want your customer to be able to do on your site. Again it may seem obvious but it's not until you write this list that it becomes clear what you need created i.e.; a shopping basket or online forms.
Think about any preferences you have as to the style, colour, use of imagery you would like or dislike. You don't have to know this but if you do have likes and dislikes it is best to make your designer aware of them before they start.
Don't be afraid to speak your mind. We enjoy the challenge of design as much as the next designer and at the end of the day your finished product has got to be and do what you need.
