Joomla 1.5 publishing website to upgrade to joomla 2.5 or 3.x

I need to upgrade my Joomla [login to view URL] into joomla 2.5. The first task will be to migrate all the joomla 1.5 data into the [login to view URL] 2.5 yootheme revista joomla template. We will use [login to view URL] Top header, vertical main menu and footer header by integrating them to our revista template in order to keep same original style joomla template. As far as component are concerned I will supply the right 2.5 3.x component for upgrade. The majot task will be to migrate all data from "MAIN SITE" [login to view URL] and [login to view URL] into the new revista yootheme joomla template and make the store work. This task does not include all subsites except """ main and store """ sites. The other task will be to migrate all feedgator component feeds from this site [login to view URL] to our new revista news feed articles AND CREATE FEED CONTENT FOR OUR SITE ARTICLES. One other task will be to use joomlaxtc newspro component [login to view URL] in order to create a special news site page with the newspro layout demo I will give you by integrating those feeds and articles. We will instal "Joobi PowerPack" components as new joomla 2.5 component like for exemple joobi jMarket Pro [login to view URL] wich will be used as new store component in order to import our riverso virtumart store data to it. When you install jMarket or jStore after install you have an option to import VM products and in the Products page, click on Import button and you have an option as well to import VM data.
