@Frank Apisa,
I would let my conscience be my guide, as Jiminy Cricket said, I believe.
I believe, diregarding actual bids, you are concerned about a) whether laborers do not speak English, and b) whether the third bid is more deserving.
The key here might be to project your thinking into the future, after the job would have been done, and feel whether you have any remorse for one hypothetical choice over another. Are you being haunted by any choices?
How will your Christmas be this December?
