is better response in urdu teaching which subject your are teaching? I was thinking that i sould start some cources in Urdu language.
Yes you may find courses in urdu as well. You will have to search with a keyword "Urdu" and will find many.
P. S I am urdu speaking as well.
Why do you want to teach in urdu language ? I see no benefit of it. Your target market will shrink down to the fraction of the whole market and that will badly affect your sales.
Go for urdu courses only when you are very good with your marketing strategies or unless your course is about teaching "urdu language" to non-native speakers.
