How effective is a 3.5 month Diploma in Logistics (IATA Certified) for a 35 yr old under Graduate to get a good job in the same field in the Gulf?

I am planning to make UAE home for the betterment of my Family and was wondering if a diploma will help me land a job with good growth potential. I have completed HSC and wanted to know if a IATA Certified, diploma in Logistics will help.
