Hello,
I have interest in to work on this project. I have experience with Angular.js and Bootstrap from my current work (besides that, I did my final postgraduate project, which was about data visualization, with does technologies among others).
I propose a 3-layer architecture for your project and as you already have a working database and the definition of what you want to see on client, I suggest the use of Django framework, which have an excellent "ORM" and good packages to provide a REST API to expose the data to the Angular component on the client. If you have any restriction about the server-side technologies, we can discuss this component further. I'm also familiar with some node frameworks and with PHP. Django is just my "weapon of choice" for this kind of job, because is simple, fast to implement and reliable.
If you have any questions, please let me know
