The first thing to do is decide where you want to work.
Who certifies you matters and some places will only accept American Red Cross certification, or only Ellis certification, etc... ARC and Ellis are the top 2 in the U.S. and in Canada it's the NLS. The cost of courses depends almost entirely on where you live and who is giving the classes. Where you live as in what state and city and even neighborhood. I found price differences of almost $100 depending on how far across town or the county line I was willing to go.
"In the United States there are several nationally recognized organizations that certify lifeguards. The American Red Cross (ARC) and its Lifeguarding program, American Lifeguard Association, the YMCA, Starfish Aquatics Institute (StarGuard), The City of Los Angeles [1], Jeff Ellis & Associates, the Boy Scouts of America, and National Aquatic Safety Company (NASCO). Many people go to these organizations to get their first aid and CPR certification that do not get the lifeguard certification." - Wikipedia
