My guess also. 

Listserv Classic license - $2,525 - $16,900
New server - (guessing) $1000-$1250
New OS - Linux - the time to configure. Windows - Windows Server 2016 Essentials - $500

So… A minimum of $5k when all is said and done. Plus someone with the knowledge & time to set it all up. (That ain’t me. I have neither.)
