Hi Employer,
I would start a eCommerce store for you, using WordPress, then I'll install a WooCommerce theme which you can choose which template which you require. You can provide me with the products pictures, pricing and details of each product and I'll put them up on the website, each with an Add to Cart function. U will be able to manage your online stationary store with ease at the backend of WordPress. Do reply to me if you have any enquiries.
