What you want to look for is something called a JV partner which stands for Joint Venture Partner. It is very common in the internet marketing industry.
Another thing you should consider is that if you are selling an eBook, you might consider selling it through Clickbank. Clickbank handles setting up the affiliate relationships and managing them. All you do is setup your website so that it will convert traffic into buying customers. Then your affiliates drive the traffic to your website. It is a much better scenario for you than trying to manage social media accounts. Social media is effective, but as you know it requires constant maintenance. You have to respond to people and be somewhat active. My advice is to build your business model so that you don't need to be an active social media person at all. You can succeed without social media. The vast majority of people selling a product like that do in fact succeed without using it at all.
