Write some Software

Looking for an experienced Shopify Web Developer. We are in the process of migrating from magento to shopify. We need to implement an integration to submit all orders to our manufacturer via their API and retrieve the order status back with order tracking number once the order has been fulfilled. The tracking also will email us if the order did not successfully process. We are also looking for a solution on if we have a certain skus placed for an order, if there would be a way to convert the sku to another sku before the order would be submitted to the manufacturer. Our amazon integration will automatically create orders with amazon skus and some of those skus need to be converted to valid skus based on a sku mapping. I'm looking to receive a quote for estimated time and cost to complete this project.
