The guy would be nuts and cussing the guy that talked him into such a guffaw.
The learning curve is large, the material is expensive, and if you are not ANAL about cleaning equipment, you will have more problems than you ever hoped for.
I would charge about 31,000 to 36,000 depending on the circumstances and variables of the job My New, 2 kit, small rig in a 14' box truck 2001 Isuzu cost me about 56,000. My big rig in a 2005 24' International, 6 kits of foam, new equip was almost 90k. Profit on my foam is around 35% gross. You do the math. No I dont think right out of school you should take on a job this size unless you have an experienced man on hand or your trainer. The devil is in the details, prep work and finalizing. Almost anybody can get a good pattern and spray the field with a coup[le weeks of training.
