Development of APP to send 3 types of documents:
1 - Contract. The user can send "N" pages.

For each document type, the user can crop the image to fit the size.

1 - Enter your purchase number (numbers only)
2 - Submit your contract. The app should allow you to scan the document, preview each page, and delete pages. It should be limited to 20 pages.
3 - sending personal document, only 1 image.
