Migrate from Joomla 1.5 to Joomla 3 Template

Hi, I have a Joomla 1.5 website for our preschool in Turkey. ([login to view URL]) I have bought a new Joomla 3 Template. ([login to view URL]) I want to migrate to the new template. No need to use the same components. But every part of the current site have to exist in the new site. New components (except the ones come with the template (free or commercial)) may be used. The template should be customized in order to fit our corporate design. The current website have both public and registered user areas which should be the case for the new site. The new site should use all the attractive modules that the original template has (of course the modules should be implemented to our needs and our content) More information and user credentials would be given in private upon request. Kind regards, Armagan Dayioglu
