Small archaeological drawing job

I am looking for a freelancer skilled in vector drawing using Adobe Illustrator to help me with a small archaeological illustration. I need to create a grave plan from an old, poor-quality photo and an existing site drawing. Most of the features are already outlined, but I am struggling with drawing the skull and some grave goods.

I am an academic archaeologist and need this completed by the end of the week. Example images of the required style are available.
