Here there is a collection of Rhino tutorials.
The best way to learn, is to do one tutorial a day. You should do each tutorial two/three times each. I suggest you to follow the tutorial the first time and the second/third time do it without looking at the tutorial.
If you practice during the holiday, you will be ready to model your project much easily very soon!
