I have a ReactJs typescript project 100% AWS Serverless stack, So I wanna to add a new component/feature, (Without modifying my current infrastructure) as my project is 100% AWS Serverless, we are using dynamodb database with Multi-table design (4 Tables), So I need your help to design a deep infrastructure diagram to Querying data in DynamoDB, in order that we can get the following tablet, and an email notification once a week (every week)

Querying request.
 for example: Naomi Cyrus, has worked 28,50 hours in X range of date, her service Rate is 10.5, and I have to paid: 299.50£
 filter by range of date and get all SP workload
 filter by Name, First Name, by Payment frequency and then with a range of dates, I want to know how much we have to pay to the SP Monica Costa, in a date range
 By the fault the table have to show the previous week from the current day

Getting an email with above table every Monday at X hours, with the records for the previous week, for example; Let's imagine that today is “Monday 11th of July”, So at 4:00 am, we should revise an email that have to contain all booking performing from Monday July 4th to Sunday 10th (the previous week)
