Airbnb + Booking Listings Sync Setup

I own and personally host a short-term rental that is visible on Airbnb. I am now setting up Booking.com. and I need help. I now need a Booking.com & Airbnb expert to give the accounts a one-time, end-to-end tune-up so I can run everything smoothly on my own...
