Aw man, this is a poorly designed survey. The amount of data cleaning you'll have to do is tremendous. I would recommend spending a bit more time up front making drop-downs for units, verifying that numbers are entered, etc. You'll actually probably save a lot of time in data cleaning this way and your cleaned data will be more accurate.
