I am new in the forum and I am willing to learn as much as I can from a premier english website!
I was wondering whether this email can be correct:

I will be available either on Thursday 27th or Friday 28th, between 9.30AM.-3.30 PM, Shangai time.
As per your request, I provide you with my Skype contact for a video conference call.
I would be also available in case you can schedule a video conference call in your Shangai Office at the specified time.

Many Thanks for your help,
