Hello,
I am very proficient at using Matlab, as I have acquired a great deal of experience building various models of my own as part of my ongoing Ph.D. and I would be happy to send some papers describing some of them as reference if you wish.
I am sure I can build an efficient and user friendly model for you, provided I have a clear description is of what exactly it is you want modeled.
Hope hearing from you soon,
