In order to be hired as a consultant, you need to provide value to your customers with outstanding quality.

For instance, being a technical consultant means that you are more experienced than the technical department of your client, and they want to get a 10 out of 10 review on their platform, design the right architecture and coach the team in the best direction possible.

Business consultants can assist the CEO and the managers by finding out the best way for them to generate revenue, grow their user base or whatever the main problem of the company at that moment is.

Your end result has to be of a great significance to your client. You can focus on areas that require deep knowledge and a lot of experience - through trial or error, or working with other top corporation - which would justify the costs for you given the ROI.
