Best Server host for the 2-week phase?

Basically just the title. I'm looking for a good host with enough power to support a big world with a large modpack for around 5 - 10 players. Having a decently cheap 1 - 2 month option would be amazing. We're not looking for any long term project, just the 2 week phase with the boys.

Up until now we've hosted using Essential but the connection is ass and it (somehow) manages to lag like it's multiplayer even when I play alone on the closed world.

What are your guys recommendations? So far I'd probably go with GGservers.
