Project description
You need to make changes: check the formulas (whether the formulas correctly calculate the indicators) and edit the rules for coloring the cells.
+ you need to help in editing the Gantt diagram in Google tables (on the horizontal axis instead of numbers specify the actual dates, the lower horizontal axis make the duration of 2 months) - this is secondary, you can take only the first part of the task.
Write in the response the approximate cost (one edit or an hour of work) and the time in which you can start to perform.
