[WooCommerce 2.0] Specifying Price in Prod. Variations String

Hello. I have an eCommerce WordPress site that has fabric for sale. When setting up WooCommerce product variations, I know the default is to show the minimum price in the string. I don’t want to display the minimum price, instead, I need the price to be picked up from the fourth line/price in my variation string. For example, if I have a product that is $20 per yard, I want the product post to read “Price per Yard: $20” rather than “From: $5” as customers can purchase products in increments of 1/4 yard, 1/2 yard, 3/4 yard, 1 yard, etc. I also want to change the text from “from” to “price per yard” for my variations. Is there an easy script that can be written to accomplish this, and where would this code be placed? Please point me in the right direction to make this change in WooCommerce. Thanks.
