Hi, for a good 'colocación', consider at least AR$ 70 per meter, plus all materials. Around 10 meters per day can be put by one 'oficial' and one 'ayudante' if they are doing a good job.
If you need a good 'colocador', let me know, I'm a local architect and could put you in contact with one. Be ready to hear AR$ 120 to AR$ 150 depending on where the work should be done and who you ask for the quote (many are handymen that quote you and then subcontract a cheaper 'colocador').
best of luck!
