what your all missing is that he is 'qualified' already. he has a 6 week course behind him, i spent years labouring for my brother back in the early 70's, and in those days is was sand and cement with quarries, and white council house tiles on the walls, now days its so complicated i'm still learning, all the new methods for the new materials and surfaces. i'm glad i'm almost at the end of my carreer and not at the beginning, you can not run before you can walk.
but to the op all the best but be a little more patient- you can not run before you can walk
