I just send samples to Ward Labs. Easy, cheap, and very fast. If I send sample in the mail on Monday, I usually have results e-mailed to me by Friday. You can just use regular 12 ounce drinking water bottles to send sample. They do a "homebrew" analysis that gives you all the numbers you need and want.
