Firstly, on a general point, I can't see anyone in the UK being interested in these US sites!
The Nursing Agency site pages are far too big - you have to scroll down for ever to read it - if you're interested that is! It would be better to have smaller sized pages with links to avoid scrolling.
The Absolute Background site 'About Us' page has rather odd text formatting.
If I ever stumbled across these sites, I would quickly find something else!
