Woocommerce Product Inventory Import

I have an Opencart based site that I want to change to a Woocommerce 2.0 based site. At the current time, I have product categories, descriptions, photos, and prices. The trick is, I want to modify the prices to fit into a tier based upon how many products are ordered. For example, if they order 1 product then the price will be x/product, above 5, y/product, 10+ z/product, etc. The quantity tiers vary from product to product. For example, for product #1 the tiers will be 1-10, 11-20, 20-50, etc and for product #2 they will be 1-5, 5-10, 10-25, etc. The quantity tiers for each product need to be scraped from another site that I will provide. A tool such as this: [login to view URL] could be used, or whatever other method you prefer, though it must allow for order quantity specific price tiers. The lowest price bidder who can show evidence of having done a similar job before will win the job.
