In order to give you a good design and concepts that achieve good results, I do need a reasonable amount of time to put some thought into it. Once that is completed, I also like to discuss possible ideas with you, so that we're both in agreement before proceeding forward.
In addition, we must take into consideration what is being done with the piece once it is developed. We may want to allow additional time for printing and/or mailing timelines. These can add an additional 2-4 weeks to a project.
