Do you host business websites and IMAP e-mail accounts? What do you offer?
Yes, we host many business websites. We offer shared hosting: https://webarch.net/shared-hosting
But for things that involve any online financial transactions you would probably want your own virtual server for additional security: https://webarch.net/virtual-servers
Or you might want to consider co-locating a dedicated server with us: https://webarch.net/colocation
We can provide email hosting on a shared server: https://webarch.net/email and if necessary we could also set up, configure and maintain a dedicated email server for you.
We can also provide sysadmin support for you based on our rates here: https://webarch.net/pricing
If you have some more detailed information about what exactly you need we could give you an idea of costs. Please contact us by email to discuss: firstname.lastname@example.org
