To offer an accurate response we need to know if you are physically moving out of Sri Lanka to another country, or if you will still reside in Sri Lanka and want to use a drop-shipper in another country.
Your account might get red flagged if you suddenly change the location of your product to account for drop-shipping. You should discuss this change with eBay customer service before making the change. They may ask for a copy of your contract with the drop shipper.

If you go this route, be aware that others are going to be using the same drop shipper and you may find it near impossible to compete with their pricing and make any kind of profit. If you don't have excellent inventory management and accurate data from the supplier that you can update throughout the day, you could face out of stock defects and lose eBay selling privileges permanently. This is one of the most common pitfalls that brings down new drop shippers.
