The rights of employees upon shutting down a company

Hi,

I have an LLC company here in the UAE. Due to financial difficulties, I am not able to run it further. Hence I have decided to shut down the company.

I want to check how much notice do I need to give to the employees. All the employees are on limited contracts. Can I issue a 30 day-notice period letter to them for operations closure?

I will give the salary to them till the last day of their service and will also provide them with airfare to get back to their home countries after visa cancellation.

Also, I want to write in the notice period letter that if at all I find any suitable buyer for the company, the company shall continue under the new buyer's name. But if no suitable buyer is found till the notice period ending, I shall liquidate the company.

Kindly advise on the legal complications involved in this!
