Hi there, I'm sure that will be able to help you with this calendar stuff. From my feedbacks you can see that I can make anything you may need.
However, this bid is a placeholder as there aren't enough details in description. You've mentioned 'Approved clients', so do you have clients section ready somewhere ? Or it should be created from scratch ?
If you already have something ready, then on which engine that is based on ?
If everything will have to be built from scratch, then there are needed more details, like fields and options for forms, reports, emails, etc.
Just contact me by chat and we will discuss everything.
Thanks in advance
