Right now we have a website built with Wordpress [url removed, login to view] .
We need to maintain the exact same actual graphics,
and to integrate an ecommerce based on Opencart.
So the idea is to have both Wordpress that Opencart, if this is not possible we have to use totally OpenCart but the theme of the site must remain identical and unchanged.
The site is intended for retailers and wholesalers.
E-commerce will have to be quick, clean and with a beautiful design.
We need both to customize the buy side and also check out by integrating the payment gateway supplied by our bank.
The critical points are:
Shipments start at different countries so the customer has to choose where wants to ship the goods.
Some products have many varieties of color and characteristics.
Everything has to be very clear and not confusing.
The back end has to be user-friendly for us.
The ability to export the catalog with ease.
The ability to export the Price List integrate it into other sites that have Opencart but also Wordpress, Prestashop and so on.
Please introduce sites that you have already created.
