We run an ecommerce business that currently runs on the OsCommerce platform and accepts credit/debit cards through Authorize.net. We'd like to integrate some API (or any API that fulfills our functionality) with our site such that customers can choose between paying by credit card or by Bitcoin.

Service must:
Allow for both Authorize.net and Bitcoin functionality
Convert USD prices to bitcoins at checkout using current USD/BTC conversion rate from bitstamp/mt gox
Provide instructions, current status and confirmation to customers when Bitcoins are received
Automatically send bitcoins to a specified wallet when a threshold is reached (or every transaction)

Payments for your time will be made in USD through ODesk.com. Please let me know your hourly rates and estimated completion time or total cost for the entire project.
