How do you organize and pick a week long retreat for small group?

We're looking to do some bi-monthly trips where our remote team of 7 can fly to another country or city and work for a week together. But it seems like all the flight schedulers are built for individuals -- kayak or google flight. And then of course we are looking to find an AirBnB that we can all stay in.

I've done some searching, but have have found a small agency that can plan and organize all of this for us. In my ideal world, we could pay someone like $50 a head to search and organize several options for us to choose from. No reselling or anything. Basically just a person/company to do all the discovery work.

Any ideas on where to go? Feels like there should be a company out there to do this.
