I've been building high profile websites and web applications for over 13 years. I'm just completing my first Ethlance project today and can put you in touch with the guys I'm working for as a reference if you would like.
I'd recommend Woocommerce because it's a lot more simple than Magento. Customizing it to integrate with your third party data API for grabbing the info needed to generate the dynamic price should be very straightforward. I've built many systems that integrate with external data so there won't be any surprises. I can build you something rock solid that just works.
I have the time, motivation, and experience needed to get this completed before April 1.
