Blueprint needed

We are a game manufacturer that is looking to have a blueprint made from an illustration of a relatively simple (non-functioning) machine. This is not for actual manufacture, but rather just to be used as a picture in a game. So the blueprint doesn't have to be functional, it just has to look realistic. We are willing to pay between $50-$75, and this may lead to more similar illustrations for the game. We would prefer the output to be in Adobe Illustrator, but we could accept it in other formats as well. Please contact us with a quote if you are interested and please provide examples of blueprints you have done in the past. Thanks! Ascora Games
