WP Engine Enterprise Alternative

My work has a WP Engine server that we are paying $750/month for.

Performance is fine and I don't care about the whole matt / wp engine drama but I feel like there has to be something cheaper.

We have around 200 sites on it but most of them get very little to no traffic. We have around 5 sites that get 20k to 50k visitors per month.

We like the WP Engine features and need something that has similar features, primarily auto back up, staging, and can easily copy sites. We will probably add another 100 low traffic sites this year so it should handle that. Email not needed.

Not looking for random hosts, they need to be well established.

Budget less than $750
