We take help from third-party consultants or internet service providers for deployment.

We did the product's deployment in-house. 

We are resellers, and we also do the integrations and monitoring for our users. So, for example, Untangle NG Firewall has a way of connecting remotely. We do the remote management for the Untangle NG Firewall, review their locks, and then send them a lodge if we believe they need to pay attention to certain things.

I handled the implementation myself.

My deployment was in-house. I never needed to contact their support team.

I can't remember how long the deployment originally took. It was less than an hour, most likely. I downloaded then contacted Untangled NG directly. I did it myself with the help of support.

One person part-time is more than enough for maintenance.
