I would like to suggest some qualities that you might want to consider looking for in your search for a “good” estimator. This is certainly not an end-all list, but it will give you some direction as to what makes up a “good” estimator:

A lot of companies are constantly looking for a “good” estimator, but they haven’t taken the time to write down a description of what a “good” estimator is. By doing this, both you and others will know what you are looking for and be able to help with identifying a person that would fit that which you are looking for.
