Urgent- Laravel Developer for an Invoice System -- 2

One of my friends helped me to develop the invoice system and completed some parts. Now he is so busy that he cannot give time. The project developed in Laravel. In this project I want to keep records of every transaction by every Patient who will come into a covid-19 test center to test their covid positive or negative. # Main Features: 1. The Registration Process: Every patient will register and pay the amount for test. (Almost Done) 2. Generate Invoice: After Registration there will be generate an invoice. (Almost Done) 3. Generate barcode: A Barcode will be generated by every invoice id for every patient. (Almost Done) 4. Update Result by a User and Approved by Another user. 5. Final Invoice will be Emailed to Patient Email 6. Result Check by Patient from web and will be able to download in pdf. 7. There will be some Reporting facilities such as patient from one date to another date, patient from a specific agent/Reference. 8. Access control the features such as one user can only make registration/update, One will update Result and admin will control all of these. 9. Transaction report for admin or related user. These are the basic ideas. Any recommendation is highly appreciated. I will provide detailed guide and sample for every steps. # I need to complete the project as soon as possible within 3/4 days. # Let me know your budget of time and money.
