This is completely possible, and will not be too hard to do. I have a few suggestions for it. If you do not hire me, I hope you still take these suggestions.
1. In the program, assign each order a customized ID. For example mtsams401234. (M.T. (initials) Samsung Galaxy S4, job order number) Of course, we can customize this later.
2. Instead of manually entering each order into the database, have the ordering script do it, and you only manually mark completions.
3. Allow you to search by phone number.
This project is doable if your server contains both PHP and MySQL.
Good Luck,
Matt Trefilek
