Needing information for International Nursing class

I am working on my bachelor's degree and am currently in a class about international nursing.

I have a paper due in 2 weeks and need to find out information about becoming a nurse in Spain. Here a the questions I need to get answered for the paper:

1. Required Educational Preparation
2. Recent Changes in Rules, if appropriate
3. Level of Education Required
4. Does licensure exist?
5. What nursing organizations exist?
6. Salary ranges for nurses
7. Median and mean income for other workers in selected country
8. If nurse wished to practice in US, what requirements would need to be met?
9. What option would you have to practice in “X” country? What are requirements?

I have done a lot of looking online for this information but it keeps alluding me, if you don't have the information, could you provide a site I can go to that is in English as my Spanish is not good.
thanks. JF
