在考查顾问时，尽可能从类似项目的客户那里得到推荐信或者介绍信，并且准确估计工作时间。
When vetting consultants, get referrals or recommendations from clients with projects similar to yours whenever possible, and get a firm estimate of the time it will take to do the job.
如果你没有任何介绍信或者推荐信的话，那就应该找你过去的同事给你写一封。
If you don't have any reference or recommendation letters, you should request them from past associates.
