Really. What were you ebooks about. Would to view them.
Yes there are some downsides to this of business but I know of a site that sells contracts them made themselves (the person did have a law degree though) for things such as proposals, web design contracts ect.... Their site makes around $25,000 a month I believe. So it is possible, you just have to fine the right market
. Take care.
