We've used laborers several times from Labor Finders, with mixed impressions. The first time we hired someone from their company, my husband needed help building an addition onto our home. The person Labor Finders sent to us said the work was too hard for what he was getting paid and wanted us to pay him more without telling Labor Finders. My husband said no so the young man left angry. It made us a bit nervous that he might come back and try to vandalize something, but we never saw him again.
The second time we hired someone, my husband needed help digging trenches for a sprinkler system. The man Labor Finders sent was a very hard worker, but he had trouble digging in a straight line. My husband strung some kite string for him to follow and the problem was solved. We were quite pleased with this gentleman's work.
If the need arose, we would hire workers from Labor Finders again. I would recommend keeping an eye on anyone you hire, though.
