BEDS24 OTA Integration Setup

I already run my properties through an active BEDS24 account and now need the channel connections finalised so everything stays perfectly in sync. The integrations I am after are Airbnb, Expedia and, if possible within the same workflow, Vrbo and Trip.com... (Budget: $750 - $1500 USD, Jobs: Airbnb, API, Documentation, HTML, JavaScript, MySQL, PHP, Workflow Automation)
