Hello,
I gone through your sample site and wanted to confirm you that we will design and develop fully functional website and Plugin very similar to Society 6 where artists will be able to upload their art prints work and able to sell through this online Marketplace.
As I have extensive experience with Wordpress/Woo-commerce, PHP, MySQL, HTML5/CSS3/jQuery, I am also expert at theme development, plugin development, PSD to WordPress, customization of WP core for development of custom modules.
Regards,
Kaushal
