"Over the recent years, I've used a variation of the phrase, "I didn't realize price was your only concern," when speaking with prospective clients who focus solely on price.
If the caller seems totally uninterested in any value-added service and is even grumbling about the price of a basic retype, you can add to the above comment, "In that case, you might try the quick-stop copy shop. They'll add no value to your resume, but they'll do it for a very low price, if that's your primary concern."
Nowadays, I get very few requests for resume retypes (most need at least an update or a rewrite), but the advice would be similar... "Well, if price is your only concern, you can find some resume mills online that will update your resume for as little as $29, but I can't guarantee their quality, of course."
