Hello,
I have gone through your requirements and seen the attached file too and understood it properly.
We have already worked on Admin panel managed by admin itself, Create/ Read/ Update/ Delete functionality, API integration, Upload images of t- shirts, Select favourite one, Check availability of T-shirts for size or colour, Payment via Paypal or Credit card, Shipping facility and so on.
I am confident enough that we can do this project and can build this T-shirt store as per your specification.
We are experts and skilled Web developer and designer and have rich experienced in PHP 5, CSS 3, HTML 5, Bootstrap 3, JavaScript, eCommerce and Shopping cart etc.
Please revert for further discussion and I am looking for your positive response.
Thanks
Nidhi
