Build me a Gantt chart for boat schedule

Need some help creating a template to generate a PDF for an operations schedule (I welcome any comments and suggestions too). I’m trying to create a berthing schedule for ships and barges, to include all hours for a rolling forecast to last a period of 7 days. What I’m looking for: • A customized Gantt chart that has a rolling 7 day forecast with hours included • 5 line items with customizable time bars – input timeframe in excel and update PDF Gantt chart automatically (line items are Wharf 1, Wharf 2, Barge Dock 1, Barge Dock 2, and Barge Dock 3). See attachment. • The ability to write in the timebar (Name 1, Name 2, etc). • Input data into excel sheet for each line item (I.e, 25 April 0600 – 27 April 1000 and have one solid line to reflect that line item will be in use for that entire period of time • I need to account for hours in each day, perhaps we can skip every 4 hours per day (I.e, 4,8,12,16,20,24) • Different colors for each line item
