yer dont do it,
you will not lean enough in a weeks course
MLA do some good training couses and you can join as a student member
trouble is the trade has bean done to death,
in my area, when i started 19 years ago there was three pages of ads in the local yellow pages , this year i counted 13 pages,
most are whot we in the trade know as cow boys, but they all nibble away at the proffessional guys,
so in terms of work you will stuggle to get many jobs,
i make my money from having retail shops and mostly from alarms and cctv these day, which both have lots of regulations so cuts down on the cow boys.
