Hi Carlos
I'm glad you are coming back to South Africa, it is indeed a great country.
I am sorry that I can not help by offering you a job. I just wanted to reassure you that with a qualification (diploma) and so much experience under your belt, you will not struggle to find employment. The accommodation industry is growing rapidly, especially after the successful hosting of the world cup.
Hotels in Johannesburg, Cape Town and Durban have increased in numbers. This will make it easier for you to find a job.
Good luck!
