Most people may look at a business consultant and think how can they tell you how to do a job that you’ve done for the past 5, 10 even 15 years, and the simple answer to that is they are not there to tell you how to do your job but simply how to run your business to maximise profits.
You can be the best electrician/plumber/roofer in the world but if your passion is in the trade rather than the business side of things you are unlikely to be able to maximise your profits yourself.
It can sometimes be difficult to know where to start if your business is struggling and spending money on a business consultant when funds are tight may seem disingenuous, however a good business consultant should be able to make you far more money than their fee and should be able to project these figures to you as an example of what they can do for you.
