I have more than 7 years of experience in PCB design , specially using with Altium and Protel software. I designed many multilayer boards up to to 8 layers and also i have experience related signal integrity issues. I have published papers related to the PCB design. Please see the paper below as one example
Sharif, A., Potdar, V. M., Singh, J., Ahmad, R. F., Nath, M., & Yang, Y. (2009, August). Processing of low level signals in mixed signal environment-a hardware design for better performance. In Network-Based Information Systems, 2009. NBIS'09. International Conference on (pp. 597-602). IEEE.
I hope you will consider me the right candidate for your project.
