Dear Sir,
I have read the attached requirements and bidding accordingly. Just one thing I think it's must to discuss 1st that, you said that there will be on going changes during the development of the site, if it will be minor changes than it will be fine, but If you'll ask for any big change and out of the current scope there will be an effect in the cost and time for this project. My bid is according to the current given features.
We have a team of highly skilled and experienced developers/coders with expertise in PHP, MySQL, WordPress, Joomla, Magento, eCommerce, jQuery, JavaScript, AJAX, JSON, HTML5, CSS3 etc and a team of creative Web Designers and QA Engineers.
Our focus is on customer satisfaction with high quality products and services.
