EMT is an entry level job. Most of these places will not expect you to have experience.
Maybe by you, but that's def not the expectation at the better agencies and better paying agencies. One of my early EMS job had an unofficial requirement that they wouldn't even look at your application until you had been an EMT for at least 3 years. They also paid the best in the county, so they could afford to be selective. They have since expanded and I've been told their hiring standards have fallen quite a bit.
Now, if you are in a place in the south, like central Louisiana, that situation might be a little bit different. Arcadian is the big name out there, so if you want to apply, just go to their job portal website:

If you are looking at non-ambulance companies, just apply to whatever you think you can do, but keep in mind it might not be anything like your EMT course. To be a CNA, you will need to have a CNA certification too, which is different than EMT.
Their are two hard parts in today's job market: getting the interview, and getting the job. To get the interview, you need a decent resume, with no spelling errors, following all the directions and filling out the application both completely and correctly, maybe even a cover letter, and you need to do whatever you can to stand out from all the other applicants. Having a hook on the inside (something who already works there and is vouching for you) can definitely help with this. Getting the job is harder, because many employers have 5-10 interviews for every one position, so you need to connect with the hiring manager enough for them to take a chance on you. Sometimes you do everything wrong and still get the job, other times you do everything write and it goes to someone else.
The first job in a particular field is typically one of the hardest to get, but we all started out that way, so it is definitely doable.
