Hello,
Thanks for detailed description, but I have to say that to deliver this project on Fri,23th, then it would require to work 12-14 hours per day. So this is like very urgent job and my cost for it about $2K. Details we can discuss via chat.
It would be a separate plugin developed from scratch and I'll be able to start tomorrow morning 7am EEST. After I finish I'll send you the plugin in zip file and you just will have to install it on your woocommerce and setup some settings (API credentials (key,etc) ) cron-job time etc.
If you are interested in my help, please contact me via chat.
Thank you for reading :)
