ISO: Live Listing Price Module

[smoothrider]

Hi there,

Our website sells gold and silver bullion. I would like a module like the "Selling Gold" module (http://www.zen-cart.com/index.php?ma...oducts_id=1091) that automatically updates my product prices every 5 minutes from kitco.com or another precious metals index. Some of my products are fractional rounds (1/10 oz silver and gold rounds) so I would like the module to be able to calculate prices for the fractional rounds. When pricing my products I would like to be able to price them as either a percentage, or a dollar amount in relation to the spot price of the precious metal.

Example:
Say the price of silver is currently $33.55/oz and we am selling a 1 oz silver round. I would like to list the product at $2 above spot or 2% above spot. So I enter $2 and the total price would be $35.55, if I enter 2%, the price would be $34.22. If the spot price jumps to $37.55, then I would like the total price to increase to $39.55 (if I entered +$2) or $38.30 (if I entered +2%).

Is there such a module out there? If not would anyone be interested in making one for us?

Thank you for your help.
