Welcome to DR1 Pierre.
Don't bother with the public/state school system unless you can fund your own living expenses while working as a volunteer - the pay is little more than pocket money.
Here on DR1 we have a 'sticky' thread in the Living Forum with contact details for private schools all over the country. I suggest you research them by looking at their websites and try contacting a few with your CV.
Private Schools
Best of luck!
