Hi There,
I have checked your project post and interested to place my bid.
I have sound knowledge of JavaScript and fortunately, I am on the process to make the video tutorial on JavaScript. If you like, I will send you 2-3 reference video for your reference. After that, if you like my video and way of teaching, I'll give you the series of the rest of the tutorial contents.
Sorry, I forgot to tell you that, videos I have made is in English. Hope this will work.
Thanks,
Chirag Khatri
