If you have your Daughter at a pre school or in a kindergarten, ask someone there , they may know, if you want to be more decreet, how about your Doctor, or a health Aid person.Have you got reading Materials in a local store on Childrens Health. The internet if you put in your Country and Town , will give you what you need. Hope all is well with you,and your Daughter.
First off let's take out the word "suffering" I have autism, but I am not suffering. What I do suffer from is misunderstanding... People may think I am less intelligent, or may treat me like I am some sub human. (lately most people I've dealt with are pretty respectful, but on rare occasions I get someone who bothers me...)
The rest of your post, I can't answer because I know next to nothing about what is avialiable in your country.
Some suggestions: be patient, and continue trying to work with your daughter to help her understand words and link them to objects. There are other things you can do, but I ca'nt say much because your post doesn't indicate what skills she shows and what she is lacking or how severe her autism is.
For me I was starting to become verbal around that age and could think words and sentences, but probably didn't do it quite as often. I knew what people were saying some of the time, at least the few memories I have. I also tended to link words to things I was looking at or thinking about regardless if that was the real meaning of the word or not.
