DV is the only resort that offers employee housing (I'm a proud alumnus of Prospector Palace). It's shitty, but for $370/mo or whatever it was it's the best option if you're just getting in to town and have very limited funds. Your first year you can live in Prospector or Silver King which are both in town, after that you have to live in River's Edge in Heber.
That being said, I'm not sure if you can get employee housing as a part time employee. Your best bet might be to work for one of the high end restaurants at DV- your experience could probably get you in the door, and that would solve your housing issue.
