Hello,
With over 7 years of working experience starting with Joomla 1.0 till 3.4.1, i have worked with all famous extensions of Joomla and customize them all.
Created many Joomla components and module, including extensions for other Joomla components.
Worked with Joomla frameworks to built responsive websites (T3, Gantry, Helix, Wrap).
My Solutions will be fully responsive and mobile ready.
Kindly allow me to discuss this with you in more details so i can see how much work you will be needed for this website that you have.
Kind Regards
Aamir Nazar
