Sebastion:
Sebastian is right: your budget is unrealistic.
You will find it difficult to produce this amount of finished chocolate for this money.
You may be able to purchase equipment used but it will most likely need extensive (and expensive) refurbishing.
One thing you may not have budgeted for: If your location does not have the necessary power (at least 400 amp 3-phase 480) the cost of getting the necessary service installed from your local utility company and your facility wired could easily cost $40,000all by itselfif it were being done in the US . I can't speak for what it might cost on the island you want to build on.
Another thing to consider at this scale (it's less of an issue in smaller batches) is materials storage and handling.
