we are developing a multi vendor delivery website (like Glovo, Just Eat and similar) based on WCFM Marketplace plugin by WClovers, WooCommerce and Ark Theme Wordpress.
All of them are not mandatory, expecially for Ark Theme Wordpress.
We are also thinking on direct php software like Karenderia Multiple Restaurant System (EnvatoMarket - Codecanyon) and other solutions.
We need initial decisions, initial customization and long term support or and better a long term working relationship, also from remote location. We are small international group, business located in UK.
