Webkul MultiVendor Marketplace

The team is very responsive and will work during US evening-overnight times to complete tasks. The app is highly customizable to your needs and the documentation is smart. It definitely takes some reading to get everything the way you need it and is very complex so takes some fine-tuning to setup. Great support though so as long as you can be patient during the day (US user), they will answer you as promptly as they can.
