Hello there,
I have read your project detail carefully, i understood the work, you want to design and build your online store in php and sql and should be responsive, Kindly share the detailed specification with us to have better understanding.
Needs to clarify some points :
Q. What are the products types or categories you are going to sell?
Q. What will be the product attributes?
Q. What will be the shipping process? Will you going to use any third party shipping API like, FEDEX, DHL for automated product price calculation in respect of dimension and shipping cost add billing?
Q. What type of Payment method you want to integrate their? Like PayPal, Stripe etc.
We are a 10 year old IT company with highly skilled designers and developers to work on php, Mysql, Jquery, Wordpress, OSC, Magento, OpenCart, Mobile development, iPhone, Responsive etc.
It would be better if you come to have a close discussion over chat .
Best Regards
Harpreet Singh
