May I know how hard is it to set-up them? Servers are set via the module and packages are under Packages?
You can enable email verification before payment: Packages > Order forms > Settings: Hold Orders from Unverified Clients
But which modules do you require? Not everyone uses 10000 modules? If you can list them we can look into them but 5.1 is our priority at the moment.
Additional perks?
Awesome, but how come you can't import over from whmcs?
