There is a strong business case for outsourcing SEO. Read the literature and understand how you can’t possibly compete with the tools a well-established reseller organization has built. Leverage your value proposition and make money from what you are good at.
The name of the game is CUSTOMERS and GROWTH. Without customers paying you, you don’t have a business. So you could spend time making a product that nobody will use, or you can get your first customer and start collecting a check today. This is why a reselling organization will really help you in the early days.
