How to get started as a CNA

I just have a question about how to get started as a CNA. I live in CA (fresno/clovis) just for reference.

Well, I'm currently in school right now to get into the nursing program but I would like to get some sort of experience while attending school at the same time. So i though it would be nice to be a CNA and work to get experience yet at the same time to pay off my college loans.

I came across this list online that listed all the places (health care centers, living homes, adult schools) to be certified as a CNA. However I'm just confused about how it all really works.

Do they have a special program just for the future CNAs? If I contact them, what would I say and how would I ask them about it to get started asap?

More importantly, if you're a CNA, do you enjoy your job?

Please help me out! Thanks
