Maria,
Your welcome. I wish you luck with finding what you are looking for. I am glad that you've put a lot of thought into your ideas, please continue to do so. Sometimes people don't think things through (speaking from experience here).
I would still encourage you to try to find culinary schools that teach basic chocolate making skills - hands on is really the only way to learn this. I think. I do know that Pam with Ecolechocolat does have a great program online: http://www.ecolechocolat.com/ where you can learn though and it is worth looking into.
I am surprised that there are no places in Venezuela that teach chocolate skills. You might look into traveling, if that is something that is viable. I know with the worlds economy as it is this may not be available to you (nor to me at the moment).
Glad to hear that you already have thought through the whole chef thing.
I would also think of a few other things - (if you have not already, seems you are putting deep thinking into your ideas), that is, consider your market or markets. Where will you set up? Will the population support you and your chocolate? Think about starting small and maybe later growing.
Several years ago I started a small chocolate shop where I live and because of unforeseen circumstances (after only 1 1/2 years) I had to move shop suddenly. I decided to grow into a larger space and it turned out that was a really bad move - for several reasons, one of which was that my overhead almost quadrupled . Because of other things I ended up leaving that shop.
And if you are looking for investment, be really careful of who you allow to invest. Partnerships can turn ugly if you do not have firm agreements down on paper.
All the best in your endeavors!
