Yes you are at the right place.
Lets start - We have the best team experienced in web design and development specially in Zend framework, CodeIgniter and CMS like Wordpress, Joomla and UI tools like HTML, CSS, jQuery, AJAX and beginner in most PHP platforms!
It would be better if you could provide
- Reference sites
- Feature listing
it might be useful for us to estimate more accurate costing, however, we can discuss and do this more clearer.
