Then you should copy how Hong Kong became so. It's very easy (for your government). For more information see:

Basically, invite a trustworthy first-class nation (like Britain, or a west-European nation) to completely govern a small region of your country for a fixed time, say 100 years. Foreign companies will want to invest their money in that region (because they will trust its stability better than anywhere else in Latin America). Many of your own people will freely move into the region, for better paying jobs and the higher human-rights standards expected from Western governance. Within a lifetime, you will have a great city that is the pride of your continent.
Transparency is a major issue. A good idea I've heard would be to ask for foreign bodies to send teams of their accountants into your country. They can help you get rid of corruption. Once corruption is gone, your country will be naturally more productive, and foreign investors will no longer be as afraid to invest more capital into your economy.
It is not smart to completely privatise education or healthcare. Both are socialised in "first world" countries. (In the past, some people traveled from the USA to Cuba to get better health care.) Likewise, environmental regulation is important (for capitalism, the term is "externalities". If no single person has ownership of the environment, then regulation is always necessary). The countries with the highest living standards are all capitalist countries, but tempered with social welfare institutions and market regulations, this is all compatible.
There is a number of organisations that have done lots of research into ways of best improving countries where the living standard is comparatively low. You should try to make use of their expertise. I'd say you want to be looking to the type of people that are invited to TED, and invite them to you.
