RN base salar

I am a nursing student and will be graduating in August with a BSN and seeking information about RN base salary and differential for nights and weekends for the Shreveport Louisiana area. The hospitals of interest are: Willis Knighton, University Health, Christus Schumpert, and Overton Brooks VA Med Center. Does anybody have any information to share? Preferably someone who works at one of these locations who can give accurate information.
