Custom Drop-Ship add-on for Magento

We are moving a site to new Magento site where we will be selling products that are all drop-shipped from various different suppliers.

We currently have a system (with zen cart) that automatically sends an email to the supplier of the product(s) bought informing them of the order and the customers delivery details.

The way the system works is as follows:
- We create a supplier in the admin area. Adding the supplier name and email address.
- When creating a product we select the supplier of that particular product from a drop down list.
- When a customer purchases a product a simple email is fired off to the supplier with the product(s) bought, the customer name and delivery address.

The system must allow for customers who may buy more than one product which come from different suppliers.
The emails sent should go to each supplier, but only contain the product bought from that supplier.

We also have an option to re-send the order manually to the supplier(s) from the admin pages. Just in case an order gets lost. This may not be an essential feature and having it will depend on the cost.

If anyone is interested in doing this for us then please get in touch and I'll be happy to discuss the requirements in more detail.
