One thing about my business, I don't sell templates. I only sell REAL content. I believe that template is only to give you the general overview of direction but not how_to do it. That's why I highly not recommended you choose to download or purchase marketing templates because I have seen them i personally think it won't help you much. Let me share you a recent story about template.
Marketing is the soul of your business, it means anything you do for the promotion of your business comes under marketing. However, without a plan or strategy your marketing campaign will not deliver the desired results. Therefore, creating marketing plan for any business is vital.
