Typing of German mathematical paper from PDF file

I have a PDF file which is a German to English translation. Unfortunately, it is supplied in scanned PDF format which is very slow to work from and the project is quite large. Because it is scanned, PDF to Word doesn't work well and unless someone has an excellent optical character reader, it would be difficult. Around 60 pages of this paper remain so if there is an expert and fast typist who can type out the German for me, that will be excellent. ** I WILL DO THE TRANSLATION MYSELF - THIS IS JUST REQUESTING SOMEONE TO TYPE OUT THE GERMAN FROM THE PDF ACCURATELY AND RAPIDLY ** I would accept the best bid from someone who has plenty of time, can do this very accurately and include the mathematical symbols where needed, since it is a maths/physics paper. Please give a bid on a per word basis not per hour. Thank you very much. A sample of the material in English (translated from German): "As for the handling of observations in the radio frequency area, here, we can distinguish between two atmospheric areas with generally differing influences on electromagnetic waves. These include, on the one hand, the electrically charged or ionized components of the atmosphere described as the ionosphere, and on the other, the so-called neutral gas components or troposphere. As well as the different refractive properties, the ionosphere and troposphere also differ in terms of their spatial situation. For example, the troposphere extends throughout the lower atmospheric layers, from 0 to around 40km, while the ionosphere begins at a height of around 60 km and stretches up to 1000 km and more."
