DC Salaries for Experienced RNs

Hi! We are planning on moving to the DC area this August. I am trying to get an idea of the hourly rate for RNs with a couple years of experience (specifically interested in Children's National, but others will help too). We need to get an idea of what this might be so we know what apartments we can/cannot afford.
Any info will be helpful! Also, any suggestions about when to apply would be greatly appreciated! Thanks
