I am looking for a duplication of an app that has already been done.

The description of the app can be found here:

This will be a much more simpler version. All I want is for a person to select a ring (we will have max of 300 rings), select a diamond size and metal, take a picture of their hand, and show the ring on it. After that, it will direct them to the website where we can close the sale.

Do not contact me if you can not complete this project professionally. There must not be any bugs. It's pretty straightforward.
