And here are some ways for you to critically compare the design firms you interview. You want someone who is excited about your particular project. Look for clues that this firm will serve you. If the people seem aloof, careless, abrupt, or disinterested, think twice about using them. You also need to feel confident that you and the designer are communicating easily.
Communication is essential to a good result.
While you and your designer may feel that you have reached a tacit agreement, every effective working relationship is built on clearly stated expectations and commitments. Your work with your designer will only be enhanced by a clearly written contract.
