Where are you located in the midwest? I have a friend who has rats in Minnesota (in a suburb of the twin cities) and I could talk to her about possibly getting a girl, though no promises. Her cage is certainly big enough though. :P

Because of the lighting in the pic I can't say for certain whether she is a siamese or a himilayan. Is her fur more of a cream color or is it true white? Siamese will have the cream coat, himis the white. I <3 colorpoints. It is definitely a good idea to start looking for good homes now. Along with CL (where, as you know, you have to be extremely cautious), I'd also post in the adoption section of this forum as well as any other rat/small animal forums you belong to and be sure to include lots of pics! Adopting to people from forums like this tends to be safer, they're much more likely to provide a good home and be educated about rats, although you obviously can't just assume this, questions still need to be asked and taking a look at that person's posting history will give you a pretty good idea of what kind of owner they are.
