Schools Advice Please (Abu Dhabi)

We currently live in Scotland but my Husband has been offered a job in Abi Dhabi. Our main concern is finding a suitable school for our 11 year old and 3 year old.
Things are made more complex as our oldest child has dyslexia , so we need to make sure that we find a school that will accommodate his needs.
I have read that it can be difficult to find school places.

We need to make a decision very soon so any advice would be gratefully appreciated!

Thanks in advance!
