Internet marketing plan for information products

[Hassan Omar]

I have added several real estate investing information products to my website. I have been able to sell a decent number of the information products each month without doing much marketing. I would love to be able to increase the number of products sales each month, but do not yet have a marketing plan for doing it.

Any ideas of where I can find a good example plan? I want to do this without creating a bill each month so please don't bring up pay for click service like google ad words.
