create html table that expands and contracts

Table for my Wordpress website: [login to view URL] I already have one database table, however i need another. it does not need to be a database, maybe a table that expands and contracts. I need the following column headers: Ciudad, Pastor, Direccion, Telefono, E-mail, Memb. Above is a link to the table that I currently have and I have attached also an example of the table rows and columns that i need. When I click on Spain I want it to expand to list all of the congregations in Spain, when i click on Chile i need it to expand to show all the congregations in Chile. I can fill in the table myself or if you need some of the data for testing let me know. I think this should be about 2 hours of work and I would like to offer $25. any offers and questions welcome
