Need a Sketch Artist

Hi- Not sure if this is right place to put this but...

I have a client who may be in need of some sketch work. He has a large product (very large, bigger than a car, smaller than a tank but not a vehicle that I am not allowed to talk about officially yet- sorry for the cloak and dagger but he insists). He thinks it would be great to get some sketches done for the sales brochure and my go-to girl is all booked up so I am looking to expand my network and find someone who is a kick butt artist with some graphic skills that has space to take on a new project in the next month. Thanks!
