It's not hard, it's super easy, but most hospitals want at least two years experience and I highly suggest at least that much experience too. Just imagine the worst patient you've ever had, now imagine having a full zone of patients like that, without help and without resources. If you think you can handle that, by yourself, then you are ready for travel. Not all assignments will be tough, but sometimes you will get dumped on and treated horribly and you need to be able to handle that.
Again, super easy to get with an agency. Just contact a recruiter, send them your documents (on boarding) and get submitted to assignments. You'll interview by phone and usually know within a few days to 1-2 weeks if you got the contract.
I recommend Fastaff and Atlas Medstaff, they are known for treating travelers well and for reasonable to exceptional pay.
Make sure you ask any and every question you can think of during your interview with the facility (patient ratio:scrub color requirement: if they have pass/cancel testing [tests they have you take when you get to your contract and if you fail they cancel your contract]), make sure you have housing before accepting a contract, if you accept a contract and can't find housing, you could get DNR'ed (Do not rehire) from that organization and/or agency. Lots to know and be careful about.
But I URGE you to wait until you have another years experience, for the safety of your license and the safety of the patients. The only exception to this would be is if you have lots of previous experience as a LPN or a paramedic.
