javascript form display, js / php coder junior level

Hi Goal: Develop a JS calculator, that displays information when a Country is selected from a drop down menu. I have a table with all countries, and information about these countries. I want to make it as a form, so that if i select the country, it will display the results. Technically its not hard, but it requires some data entry work, to add the information for the countries, I am looking for a junior level js/ php person for the work. Prakash
