This actually depends on which is your question. Consultants won't do magic, they would just help you understand your business from a different perspective and give you advice based on past experiences and predictions of what they think it could happen.

E.g: Here in Clarity I got a question about how to promote a film deal. After talking to the person he told me he would have a premiere that was sold out already. I told him to extend the Q&A outside of the premiere and into a bar. To create a more close experience with his audience to obtain feedback of what they thought of his film (product). He should also obtain all the contact info of his audience. Once you do this, it's easier to address to them. 1-You know them better 2-You have their contact info
As you can see this is very specific. The same should be your request to a consultant
