As far as applications go - it seems everything is done on line these days - they ask for the usual, name, education, job history, description of duties, references.
Shift differentials can make a huge difference in your paycheck! But doing nights doesn't agree with everyone.
I don't know about paying to have your application "processed" - I wouldn't since there are a zillion ways to apply for free!
Shifts - days, evenings and nights are the usual trio. The times may vary but usually 7-3 days eves 3-11 and nights 11-7.
In terms of finding jobs the internet is an excellent resource. Here are a few sites some are better than others :
www. America's Job Bank
plus monster.com of course.
plus the classifed ads in you r local Denver paper are on line so look there.
You ask about pay - I don't know CNA wages - but another web site is salarywizard.com - should be able to fix you up.
So I hope this helps...
