Research lowest prices of products on Japanese websites（投稿ID : ja3b）

I'm looking for someone from Japan to help me research the lowest prices for 36 products in Japanese online stores. I have a list of products (ultra-cool Japanese writing supplies - yeeaahh) and I'd need the price and website address in the list. I'd imagine it'd take about 3 hours if you speak Japanese (which I obviously don't :) ). Payment could be arranged via Paypal (or any other way you'd prefer). Thanks a lot!
