Need help formatting an excel Gantt chart.

I am looking for help to format an Excel Gantt Chart. Specific formatting changes that are needed include color coding, adding milestones, adjusting column widths and adding formulas to track the progress of each task. I have specific colors in mind that I would like the chart to use. Lastly, the Gantt Chart will include less than 10 tasks. If you think you can help me with this project, please get in touch!
