A consultant works with the management of a business to improve the profitability of the business. Working with the top management, you can rest assured the consultant is a very highly paid individual. Some consultants charge $100 per hour. Others charge $1,500 per day for their services, and still others work on an annual retainer fee of $12,000 to over $30,000 per year from any number of large corporations.
Until a few years ago, the title "consultant" was more or less limited to retired diplomats and top corporate officers. In other words, until recently, the consultant's position was honorary than actual. But that has all changed dramatically in the past few years.
