heheeeheeeeeee. No one was answering and I'm not above shameless self promotion. I have to put in another check mark for what everyone else is saying here. But I'll just throw out that not only does style come into play here but the price is also probably dictated by what exactly you're trying to accomplish with the drawing. If you're trying to work out your own idea kinks and don't need a complete project design is one thing .... if you're going to need to see exactly how the seats are stitched and how to bend the exhaust then you're probably going to pay more. If you just need someone to show you something unique because you don't have the time to dig through or maybe you aren't sure how to make it stand out then there are plenty of creative people who can do that fairly inexpensively. But I have to say fairly. Drawing in any medium is time consuming and you're paying for ... hopefully ... someone who spends a lot of time keeping up on what is current in this industry.
