You do NOT have to spend money!
But you do have some learning to do, and you will need help with that.
I am presently a few posts into a series of IBO posts as to how you can use free resources to make this work.
I invite you to visit one of my recent IBO posts "Internet marketing made easy!" (a detailed recap) for help on getting started for free.
Use IBO, it will be a big help.
Much success, my friend.
