I have read your project description, and reviewed the extension, and i understand what you need. However only available version of the extension is not Pro, so i will need your Pro version of the extension. I have strong knowledge of Joomla, and technologies used by Joomla (PHP&MySQL, HTML&CSS, JavaScript, XML, ...), and over 10 years of experience in web development, and administration, so i should be able finish this project without bigger troubles and on time. If you have any question or more information, please don't hesitate to contact me by private message, thanks.
