Linux System administrators specialising in web hosting

Linux sysadmins!
I am looking to consolidate a number of shared VPS servers hosting websites (WordPress, email, ftp on cPanel) to a new Linux Ubuntu VPS running Hestiacp.

Looking for someone who can work with me to
a) Ensure new server is correctly setup, firewalls, spam filters, DNS, SMTP server and whatever else to harden server
b) Migrate websites with email to the new server

Not a massive budget on this but way I would see this working is by task level that can fit in with your existing commitments.
