When you live in the Netherlands and your Dutch is okay, you could consider to take a course at the Del Ferro institute in Amsterdam. I've done the course years ago and my speech got better. Some of my classmates turned to almost fluent. But, it takes a lot of effort. You have to commit to follow 'the steps' for a serious period of time. When you do that, they claim everybody can speak fluent. When you have questions about the course, you can contact me. Take care.
