Hello,
I have built my own pentest lab at home with VMs, a second computer and an additional Cisco router. I believe I can help you with my experience as well. I already know how to set up security testing tools on Kali, including but limited to setting up Snort with its signatures, bWapp, DVWA etc.
The time required may vary depending on your exact requirements.
Furthermore, I have been professionally working on IT Security field for almost 5 years. Therefore, I have a solid knowledge on industry-standard tools as well (e.g. SIEM tools, Akamai Luna, Symantec DLP etc.)
