Bonanza Order Sku match to Netsuite fields

You must have experience with Netsuite development and be available at some point between 9am-5pm EST daily. We also ask your price includes 30 days of technical support after job completion. We have a PHP script that imports Bonanza orders, but it does not work for orders where the sku is something besides our Netsuite internal id. Your job would to add code to make the orders import to an item based on Bonanza sku by checking internal id first, then a custom field, then a second custom field. If Bonanza sku does not match any, then script should send an error email to us.
