How to determine which dry cleaners to go to?

I moved to a new area and usually launder my own clothes so I don't know much about dry cleaning. I called a few dry cleaners in my area. A few answered my questions: hours of operation, is there parking, do they offer discounts, shoe repair, alterations, and prices of certain garments. Others refused to give prices over the phone. One actually became offended "What is this about?!" even though I explained I was calling to offer my business. I had used one of the dry cleaners but did not have the full price list, but even then she told me to come in. Some of them claim they don't know the price of garments and give me a vague number $4 or $5. WTF? Even if I decided I was going to go to the closest dry cleaner, I still need to know how much I'll be paying. Is this evasiveness a function of the industry? Isn't an honest business up front about standard prices (not extras, just a standard minimum price)?
