Microsoft Excel Expert for Shift Management System

We are Healthcare staffing agency,We have Clients with many branches,Epecially one specific client who give us their requirement manually and keep details for themselves in house on their Calenderpedia.co.uk which seems like an excel. Im looking for a Microsoft Excel expert,Who can creat a User friendly system that matches their format which I can share with my Clients,Where they can post available shifts with minimum effort with live access with specific branch having access to their personal sheet not shared with any other branches and having access to themselves ,our agency and Regional director for those branches. Now how they work is: They give us shifts to cover via email or WhatsApp. We book candidates via sending them booking confirmation email and WhatsApp msg They than go to their Calenderpedia.co.uk where they have color coded days and enter the name of staff we have booked, But then they also have to mention separately to their accounts that which agency provided staff (thats us) I have the sample of the calenderperdia they use.I also have sample of an excel sheet that my other client gave me,I think if we can combine both and make it so user friendly and give that to my client to use... First of all it should seem like the one they are already using and nothing new,But with extra feature and save time for them Hence making client addicted to our selves Also must have some sort of live communication Apply tot his job Apply To this Job
