Dear Concern,
After reading your details I understood you want a online shopping site.
As a senior software engineer I can do the work easily using open-cart CMS. Which is more flexible and user friendly. So you can easily maintain your all the works.
I'm working in PHP, MYSQL, HTML, CSS, JAVASCRIPT, AJAX, JQUERY for more than 5 years.
I believe in quality work with minimum price. And I'm confident to complete the work.
Looking forward to hear from you.
Best Regards
Nafiz
