I have couple of good quality web applications. Personally I never got time to market them. I am just a web enthusiast who love to make web products.
Is there any good market place other than Flippa where you can put up the products for sale ? At Flippa people are more interested in buying running businesses with proof of revenue. In my case, I don't have revenue but the product themselves are really of good quality. With a little marketing, it can generate good income.
