Create a graphics/illustration for an agricultural show

AGRI FARM Maschinenbau

We are manufacturer of tillage equipment for the agriculture.
Our main market is Austria. A huge export market is Germany, we also export to Hungary, Romania, Switzerland and France.

We want to have an illustration/graphic for a backlit back wall at an exhibition.
The backwall is a textile which is backlit with LEDs and has the size 15x4 meter.

This graphic should contain our machines working on the field, our logo and it should show a agricultural landscape, perhaps in the background a farm house (and a farmer).
The design could be also more like an illustration -> in the past we made a tin sign with a kind of retro design (please have a look at this tin sign).

Maybe that would be a good arrangement:
3 machines more in the front which are bigger presented, and 3 machines which are more in the background (also perhaps with different sizes)...
The logo middle on the top.
The backwall is directly standing on the floor, so it would be better if the machines on the graphic are not directly positioned at the bottom. Otherwise the graphics would be too much hidden by our exhibited products.

I have enclosed our company logo and some product photos.
If these photos are not good for working with (cause of resolution or other reason) I try to find other photos.
"Rueckwand.pdf" is what we roughly meant.
