I am an Engineer by profession. Actually my academic study is on EEE (on going). I am working on software engineering field. I also work on Web Page Design.
Here I will work for you to Design PCB layout. I also have an expert for complicated design.
I believe $5 is very reasonable for a small schematic. However, I believe that it is important to mention your expertise in PCB design and layout. For example what sort of circuits can you design since digital circuits and RF circuits are very different. Also, PCB layout and routing of multi-layer and dual-layer require a higher level of skills. Anyways, cheers and best of luck.
