Message me if you have an option. Thank you.
All the precautions and security measures as you prefer.
You can try the UAE's bitOasis exchange. Their rates are more reasonable than offers on Localbitcoins and you can pay either by bank transfer or by credit card.

That's like 56 million dirhams. Nearly 15 million USD cash. You can't be serious.
I would definitely recommend sourcing the coins from an exchange... unless you want to move those 56m AED without using banking channels (for whatever reason and I won't even ask or probe further).
