I'm not from US either, but I have access to him. There are many ways to get the book if you want and you could try asking him as he has given his book to students for free. He has a YT channel where there are some videos you should find interesting [https://www.youtube.com/c/LeeLovettSpeechWhisperer/videos](https://www.youtube.com/c/LeeLovettSpeechWhisperer/videos) He will not be able to do this forever so he have trained some other people in using his methods and they try to establish a community / place where other can get help https://worldstopstuttering.org - Currently this is the closest to online course you can find.
