Twilio Expert Needed for Python Script

I have a Twilio account with 3 accounts in it (when I login with my email there are 3 accounts in that one main account, and one of the 3 accounts has numerous sub accounts. It is really difficult to sift through in Twilio to find out which account is costing me the most. I am looking for a Python (or Powershell) script that will give me the last X days (do an input line to allow me to enter the number of days I want) report for each account, and sub accounts, and output them to a csv. I want the output of billing information, meaning number of texts, calls, etc. for each sub account on each account easily readable in a CSV so I can see for the last 30 days, each Twilio phone number, and what its costs were. Twilio knowledge is important as well as some Python. I don't need a GUI, just Python 3.7.3 compatibility since that is what I am running. In your bid, please put Twilio at the top of your bid so I know you read this and understand what I need.
