freelancer app developer

I have a small home service business. I want someone to create an app that will let my staff put in the receipts as soft copy receipts and also take the costumers signature. Also, I would like the app to track the monthly income and give it to my as a scatter graph. The app should also have a place to put in the business's expenses. Finally, I would like the app an editable calendar or schedule and the ability to send me the graphs to my email.
