Anyone know how to do this for FREE?

Depending what you mean by free. The process is documented by apple and you can google "apple boot camp" to deploy it on your machine for free. However if you are looking for someone to tell you how to pirate a copy of windows you won't have much luck on these forums.
 
If you don't have a license, can't you just re-image like once a month right before the "trial" is done and it will reset it? I'm not sure, I just remember hearing it somewhere...

But if you are going to be using it on a regular basis, you should just buy a license.
 
If you're a student, you could check whether your university participates in the MSDN Academic Alliance and how you can set up an account with them.
This way you can acquire a free copy Windows legally.
