convert c++ MFC (win api) charting app to qt ubuntu + opengl


I have an application written in c++ MFC (windows) and i need it converted to c++ but to run on ubuntu (qt). The application currently uses win api to paint 2 types of 2d charts + some arrows. I need it changed to use the graphic board (opengl) because the amount of data is huge and the app doesn't work smooth when scrolling/zoom in or out. The app needs to smoothly work when painting over 10m points.

The app currently takes it's data from a postgresql database but since the amont is huge i need a better way to store it so that it's loaded faster when the charts are painted. So the project winner will have to update this too and propose & implement a better sollution to save/load from the db. Currently all data is saved plain, each field/timestamp has a coresponding field in the db.

I also need some small modifications to the orderbook charts (these are done already for the simple graph type) and include painting arrows and overlay other charts over the orderbook chart.

I need somebody very good at c++ and experienced with opengl. An incomplete solution is not a solution so i will pay everything at the end after project completed. Please don't bid if you think you can't finish this or intend to do half a job. I posted some pictures with the charts my app can paint so you can make an idea.

thank you and please don't bid before reading!
