pull data from shopify website using perl script - open to bidding

I would like you to modify my shopify theme using perl script by enabling the following: Create a backdoor login for sales reps and to track sales commisions Each Sales rep will be assigned a unique discount code When someone uses the sales reps discount code to buy something for example David 232, the customer gets 15% off and David gets $5 deposited into his account for each sale as a commision. David the salesrep should be able to have salesrep login account to check the amount of sales commision he has earned and this information should be updated in real time. Whener someone makes a payment using David's code he should get an email alert stating he just earned a sales commision. We should be able to print a payment invoice monthly to pay David. That is it
