I totally agree with this and have done it myself. I've also been on the receiving end of this when I actually do know the market / tools better than the consultant and I actually do know exactly what I want, and the consultant has tried to brush me off. That does not end well for them. Just a word of caution to take extra care to know the background of the person you're talking to before starting down this path :)
