Know your project
You may not have any specific outcomes in mind during the early stages (perhaps that’s why you’re looking to hire a creative agency in the first place), but you should at least try to establish some basic aims or goals before beginning your creative journey. Having a rough idea of your budget is also useful (if it’s a flexible budget, even better – agencies are likely to put forward some additional ideas which may well take your fancy).
Feel free to put together some examples of any work you find inspiring – although not essential, inspiration can go a long way towards assisting your chosen agency in understanding the style and tone that you wish to capture. Last but not least, keep in mind a deadline for your project. Timescales will vary based on the size of the job, but it’s always best to allow plenty of time for completion.
