Think through the pricing model of the hypothetical web site you propose in the last sentence - that is my point.
If a web site charged $500 and was very easy to implement, I could do it as an experiment and not lose much if it failed. If it succeeded, that web site could charge me again and again to keep doing it, and I would be happy to pay.
But if I have to spend $8000 and several weeks up front, I'm going to be very cautious. It doesn't matter if that money and time are spent hiring someone or purchasing and installing an automated tool.
"I'm not saying that there isn't a person out there who can revolutionize my marketing in 20 minutes" - I'm saying you wouldn't pay them to do so in line with what doing so would/should be 'worth' to you. There is no market to pay to revolutionize your marketing in 20 minutes, at a pricing that is based on what it should be worth for you to do so. Doesn't exist. You wouldn't pay it. Imagine what "revolutionaizing your marketing" means, image what "revolutionizing your marketing" would be worth to you - do you have that figure in mind? Now imagine paying that to someone for 20 minutes of their time. You wouldn't. Neither would anyone else. That market doesn't exist.
