Need some advice on a guide I'm selling

[johntrichfield]

Hey guys, I'm compiling a guide on how to get free online courses and MOOCs. I'm going to sell it on ebay, but I don't want others copying it and selling it too, as it has and is taking a lot of work to put together.

As of now, it's a google spreadsheet and a couple google docs that go with it. Both of which can be copied in seconds.

Should I just leave it as that and hope nobody copies it? I've been thinking of creating an application that displays the guide, and I could make it very difficult to copy. What do you guys think? Is there another solution I'm not seeing?

Thanks
