Hello I spend with you the costs of what I would charge for the standard jobs you mention; I say with reservation, because I know that the work done in certain parts of Buenos Aires or other large cities can be charged much more than I will detail. Labor costs, reference: interior of Santa Fe. (Said in plain, what it would charge) * Placement of goalkeeper visor in replacement of an existing one (external front) and without extra difficulties in the internal viewfinder = 700 pesos * Change of keys in two mouths = 450 pesos * Turtle placement = 380 pesos * If we need to wire that luminaire (turtle) = 200 pesos * Double thermal placement in 2/4 din pvc box for direct operation of small motor (not including cable-to-pump installation) = 400 pesos In half a day you have to spare time.
