How and where to search for employment

 I am a graphic artist who wants to know how and where to find a position or work as a scientific or medical illustrator online or else where.

Major Employment Search Engines are a possibility, but I was hoping for more.

I am just beginning. I have produced more logos and graphic design, but I've studied Figure Drawing, Acrylic and Oil Painting, Perspective, and Drawing (Illustration) while attending college.

Thank You (anyone here) for any advice, or leads.
