Gantt chart script for occupation laser cutting machine

I am looking for a freelancer to write me a script based on my current schedule I use for monitoring the occupation on my laser cutting machine. ----Demands---- There are 2 types of cutting plans, manually and automatically. Manually cut programs - Maximum working days Monday – Thuresday 7:30-16:15 - Maximum working day Friday 7:30 – 15:15 Programs that are cut in automatic mode in the late hours, after 16:15, maximum 12 hours. The bar of the Gantt chart is per minute. Start of the Gannt chart is always now / live. The operator is free to start any program of the list, so all started programs (can be multiple) are first in chart. We can added a expected finish time when a program is put in production so we can start planning after that entry. Starting with the cutting plans that are already behind schedule. Then the programs for today. The programs for the future, our schedule runs now already up to august should be automatically be filled in. So we are able to see at what point in the schedule we can fill in new programs. If there is space in the chart between programs, different programs with the same material and thickness should be attached together for an optimal occupation. The database (MySQL) has the following information available: - id - cnc number (program number) - material and thickness - client name - material and thickness Attached I have added an example image of an Grantt chart and the current schedule wich is only based on finish date. Refresh chart every 15 minutes.
