I need a web app developed that allows for secure access to the database at various user levels

I use Microsoft Access for patient record keeping via Remote Desktop Server. All employees use the software at various permission levels. However, maintaining Access has gone beyond efficient. I need the access split database to be converted to the free version of MySqul, Queries recreated as Views, and a new front end built for User Interface and report generation. There are approximately 40 tables and approximately 20 views. This will greatly be reduced by migrating to MySQL and a webb app.
