I WANT TO CUSTOMIZE A LARAVEL WEBSITE

I want to customize a school Management to make students pay from their dashboard to generate a 16-digit PIN before they can access their termly/semester result. Without the 16-digit PIN, they wont be able to view their termly result and any PIN used for one term/semester, cannot be used for another term/semester. Same procedure applies to parents who may wish to check their children result from their dashboard. I will share the demo link of the website in question. My budget is minimal, so please be considerate in your biddings. Thank you
