Magento2 very quick US$10. Just save/append *ALL* order details to a file whenever a new order comes in. This must be a magento 2 module following all rules of magento2 module and NOT magento 1. Very simple.. payment US$10 only not more not less. Can be done in 30 mins I guess. You can serialize the order object and append to a file.. That's all. Simple isn't it .. Too simple for US$10 but I am generous.
