We are a team of designers and developers with expertise and experience in Web designing, HTML, CSS, PHP, AJAX, JQuery, XML, Wordpress, Bootstrap, CodeIgniter and MySql. We have developed many custom sites and applications of varied extents and complexity, including many e-commerce sites. We have also developed a site recently where members can buy using credits/ points - http://www.loyaltyrewarded.net.
I have read the requirements and am confident of delivering well. I however request you to share access to the existing site / system where the add-ons need to be integrated. This will help me to assess scope of work precisely. I will revise / confirm my bid accordingly. Detailed specifications and inputs will also help me to make an informed commitment and deliver as required.
I ensure a very thorough job and also support if you need changes / enhancements in future. I look forward to hearing from you and working on the project.
