Hello,
Good day, We have created such system, a small scaled school fee system ,and we are good expert in php/sql based systems, I can arrange login and backend panel for your reference as well. We also have good idea of rtl, since worked on multi lingual projects so it had that requirement.
We also worked on some similar systems as below.
1. School Fee System
2. Fiancial System.
2. Daily Ticketing System.
3. HR System
4. Inventory System
But honestly your budget seems quite low, but we can still offer you a price of $500, which is very very nominal, andI have seen some people are giving budgets for $150-$200 etc, so I would really suggest you not to go with such prices as your project demands more work and under this price I don't think so that you will get a quality work, and you would need a quality work since its a day to day system.
Please feel free to let me know if you have any questions.
Thank You
Best Regards
