You might want to contract with a consultant for this. A consultant could either supply you with a finished product or tutor you to the point where you have created your own solution.
You can, of course, pursue a solution through this forum. That will require more time on your part but save you the cost of hiring a consultant. If you choose that route, please post a more detailed description of your business procedures and what you need to do so that those of us who choose to can better assist you.
Another option is there may be a ready made solution that meets your needs or which can easily be adapted to meet it. If you describe your needs in more detail, a forum participant may be able to suggest such a "template" for you to use.
The thought is to start with a professional template that gets you close to what you need and customize from there because that will cost far less than to start from scratch.
