Sound Engineer Required to Design Motorcycle Sounds

We are an electronics design company and for one of our products we require sounds of different motorcycles in WAV format. For each motorcycle we would require 1) Start Engine Sound 2) Idle Engine Sound Loop 3) Low RPM Sound Loop 4) High RPM Sound Loop 5) Stop Engine Sound The sounds do not necessarily need to be realistic or emulate real motorcycles. We will be storing these sounds (WAV) in the memory of our electronics which will then be responsible for manipulating the sounds depending upon the RPM of an actual electric motorcycle and fade sounds in and out, modify playback speed etc., as the electric motorcycle moves along the RPM range. We are looking for someone who has experience with vehicle sounds and probably designed sounds for racing games. We are only looking for sounds for one motorcycle first and if we are satisfied with the result, we are planning to create 10 - 12 more. Hence, please quote for a single motorcycle. For reference, this video ([login to view URL]) shows a similar product (for cars) which is what we are looking for.
