Pixelmon Server Host

I am about to release my server and i am going to be going with Zap Hosting as it’s cheap and offers a lot of RAM but the issue i have is don’t know what package to buy as there is a package called Minecraft:Forge and a package called Pixelmon reforged run through technic launcher.

I am running Pixelmon on Spongeforge 1.15.2 so i need to know what seerver i buy to host it on

SpongeForge doesnt have a version called 1.15.2 nor does it run on Minecraft 1.15.2.
