Your best bet would be to find a company that will transport your products to Qatar (or if your distributors can send them directly there). You’ll also want to check into the local laws there to see what can/can’t be sold and what can/can’t be imported of your products. Most importantly, you’ll need to find someone that you trust with your business that is willing to move to Qatar… if you hire someone in Qatar without meeting them or working with them, you’re asking for trouble as you don’t know if they will represent your business well or if they will take all your money/products and run. Y!A is probably the worst place to look for a business partner like that (not to mention it’s against the rules to solicit like that).
You should also be aware that there are health food companies that sell foods and supplements in Qatar as well so you will have competition. Good luck and I hope I helped!
