To complete your task, analyze the table image and identify the positions of the specified cells. Ensure that you represent a cell's location using the JSON format {'value': '<cell value>', 'location': (row number, column number)}, with both row and column number starting from 1. Represent the location as 'DOES NOT EXIST' if a cell is not present in the table.
Target cells:
1. 'Gloucestershire College';
2. 'Bence Building Merchants';
3. 'Duraflex';
4. 'Towergate Insurance';

The target cell locations are as follows:
1. {'value': 'Gloucestershire College', 'location': (18, 4)}
2. {'value': 'Bence Building Merchants', 'location': (14, 3)}
3. {'value': 'Duraflex', 'location': (5, 3)}
4. {'value': 'Towergate Insurance', 'location': (13, 3)}
