Help converting SUV into CAMPER VAN

Oxnard near Laurel Canyon, Los Angeles CA

Description

I need someone with experience to help guide me through the process. It's a minimal conversion with only storage and bed (no running water etc.). I want something similar to the picture but the side storage won't go all the way to the roof. I already have plans drawn up but I need help executing. For example, I need someone with experience drilling through the car's metal frame to make a solid mounting point.
