Convert Articulate Studio e-learning course to Articulate Storyline

As a result of a new customer requirement I have some Articulate Studio 09 (Presenter,Engage,Quiz) courses that I need to convert to Articulate Storyline2 (for HTML5 for users to access from any devices), re-using as much content as possible from the existing courses. The content is currently 6 modules with about 45 minutes screen time per module. I'd also like to add functionality such as using variables to have dynamic content depending on job role of the user. I have the source material for the existing courses including Powerpoint, Articulate, graphics, audio, video etc. I'm looking for suppliers who have previous demonstrable experience of Studio to Storyline conversion work to express an interest and I'll provided more details to short-listed suppliers. Please respond as soon as possible with details of previous specific experience of Articulate Studio 09 to Storyline2 conversion work.
