Hi,
I’m really @lufi asked this scenario, because shows how flexible Mautic can be.
In my opinion you should take advantage of the “contact ownership” concept built into Mautic.
1. Create multiple users in Mautic
One for each role you’d like to have: info, sales, support.
2. Assign owner
Once a person fills out the form, you can assign contact owner as a campaign step based on the radio button choosen.
3. Send email to user
From this moment you are able to send email to a specific Mautic user as campaign step:
Make sure you are turning on the switched called “send to contact owner”
4. Contact ownership is everywhere
Contact ownership can used in conditions, you can change via campaign steps. You can send email to user via Forms
5. Set identity in emails
Sender identity can be set as “send from owner” on any email using the advanced tab!
+1: Contact ownership can be used in tokens
WHAT? Mautic can do this? Sure it can 
In many areas of Mautic contact owner’s data can be used as tokens:
I think this can be a good video tutorial one day.
Let me know how this works out for you.
