RN pay scale Texas Children's Hospital field/home health, IV infusion

I am a RN with 14 years experience. I have been recruited to Texas Children's Hospital home health IV infusion . I was told by HR that they will make an offer of employment Monday. What salary range should I expect? Does a salary grade 11 seem right? If so, how much is that?
When HR makes an offer, do you recommend I counter with a higher salary or take what is offered?

Thanks. :confused:

Yes I would! Everything is nagosable. Also call around to other home health agencies & see what they are getting. I have seen $45 to 60 per hr.
