Hello Martindr, I just refused your invitation, but I don't want to do that without telling you the reason.
At this moment I do the reviews for about 140 members of Livemocha (a language-learning website on internet. I am Dutch, but also speak German as a native, fluent English and advanced French. And I am learning Chinese Mandarin. I also teach many Chinese students on universities in China, Germany and Holland better German and Dutch. That students, I teach in privat on msn internet very intensive. Five days a week I do this for a young Chinese woman who is a professional teacher in China for Chinese language and literature. And she teaches me Chinese. So you see I am extremely busy and have no time left to teach other ones. I have to refuse every day about 5 new students who want me as their teacher. I hope this explanation let you understand that I can not take you. If I take a student, I want to teach him good, so take enough time for him.
If you realy want to learn Dutch well, take a good course to study every day. Together with that study look for a good native speaker and teacher to help you with speaking and pronunciation. Just in that case you will learn this language good.
I wish you all the best and good luck !
Jo
