When some guy comes along and says I can double your earnings and will only charge you half of that increase when it happens, then stop and listen.
There are too many factors in "doubling your earnings" with many completely out of control of SEO service companies. So no wonder you have not met that first guy.
What if your back end fullfilment or your customer service is not right? For someone to offer the above, they would have to have a lots of say on how you run your business (and not just your "front end web business").
