One of the hottest niche markets off the Internet marketing field is reprint rights. Everyone wants to have their own products without having to create them, themselves. Basically, reprint rights are products people have created like ebooks or anything digital usually and they allow people to buy rights to sell the product as their own without having to give any money from the sales to the originalowner.
Reprint rights sell from as low as $17 to as high as $15,000 and more.The idea for this business is to be the middle man when people are looking for reprint rights. You could create a site that allows people to advertise the type of reprint rights they are offering to their product and you could charge them a set fee or take a percentage of the sale.
This is sort of like the first business idea, the difference really is the market.You could even set it up as a membership site. I know I would pay to join a site that had honest reviews on reprint rights for sale. Become the central hub for people looking for reprint rights and for people looking to advertise their reprint rights.
