Look at the provided table image. Your goal is to find the locations of the specified cells. Remember to represent a cell's location using the JSON {'value': '<cell value>', 'location': (row_id, column_id)}. Both row and column id begin from 1. Denote the location as 'DOES NOT EXIST' if a cell does not exist in the table.
Target cells:
CELL VALUE 1: '10,600';
CELL VALUE 2: '$550';
CELL VALUE 3: '20,000';
CELL VALUE 4: '$710';
CELL VALUE 5: '11,900';
CELL VALUE 6: '1,200';
CELL VALUE 7: '5,900';

The target cell locations are as follows:
CELL LOCATION 1: {'value': '10,600', 'location': (4, 2)}
CELL LOCATION 2: {'value': '$550', 'location': (5, 1)}
CELL LOCATION 3: {'value': '20,000', 'location': (2, 2)}
CELL LOCATION 4: {'value': '$710', 'location': (6, 1)}
CELL LOCATION 5: {'value': '11,900', 'location': (2, 3)}
CELL LOCATION 6: {'value': '1,200', 'location': (6, 2)}
CELL LOCATION 7: {'value': '5,900', 'location': (5, 2)}
