I am going to ask you to ready one book if you want to market your business on your own – Ogilvy on Advertising (affiliate link). Why? Because everything Ogilvy did was about delivering a response.
In other words, there are no budgets for branding. You are not Coke or Pepsi. Every dollar you spend on advertising has to come back to you dressed up like a $2 bill.
And Ogilvy hated the creative types who could burn through ad budgets faster than Grant through Richmond. So get the book and learn something today.
