Opportunity to move to Raleigh from UK

Hi,

My company is considering transferring me from the UK to our office in Raleigh NC. My wife and our 1-year old would be coming with me.

I have a few questions:

1. What salary would I need to be offered to support my small family in Raleigh?

2. How is Raleigh for young children?

3. My office would be in Clayton, where would you recommend living?

Thanks!
