Need server properly setup asap

I am looking for someone who is very familiar with virtualmin who can go through my vps and set things properly. my 1 website shows up. but my other site does not and webmail and admin logins are not working. my 1 server uses ssl and should be dedicated ip. where 2nd ip should be for newly added domains yet or keeps trying to use the ip address of my dedicated ip. not looking for a walk through. I just need someone to fix this asap for me. or if you can suggest a company that setup virtualmin with ubuntu 18

thanks
