However, the answer is very dependent upon the group that you are going to work with. Even though automated tests are worth the investment in nearly every situation, how you explain it will not be the same. You're going to need to see how people are doing their work now, how they mitigate risk, how successful they currently are at mitigating risk, what the cost of their efforts are, etc, etc. You're also going to need to see the people involved and chat with them about their attitude towards testing and try to understand what kind of challenges you will have to move in that direction. Because it is entirely possible that you will say, "OK, let's all write automated tests" and spend a huge amount of time and money only to find that 3 out of the 5 team members refuse to do it and sabotage your efforts.

My answer to that question would be, "I will be very happy to. My rates as a management consultant are $X per day." :-)
