I'm not sure where you should look, but just wanted to warn you that working with elderly people often puts a huge strain on your back so don't go that way if yours isn't in fantastic shape. All the people I know who work in this industry have had time off due to back injuries involving lifting or falls.

You can earn great money in this field and as the population is growing you will never be out of a job once you are trained. Good luck with it all.
