Do you fix your own car? How about re-shingle the roof of your home? Do you call a plumber when you have a flood or try to fix it on your own? Do you try to perform surgery on yourself? For most, if not all of you, the answer to these questions should and will be no.
So it doesn’t make sense that being a professional service provider with little or no experience in marketing, you would try to go it alone. Does it? That would make about as much sense as your clients going to court to argue their case, or writing a crucial legal document on their own. About as much sense as them defending themselves to the CRA or trying to make sense of all the complicated income tax changes.
So do what you do best and look to others for the rest.
