I will suggest Eagle to you.Eagle is my favorite for board design
simply because of how user-friendly it is.
Proteus is an all in one product from schematics to board layout
through to simulation on a high level. Eagle is schematics and board
layout design software only, no practical simulation.
Eagle is the only real solution out there. There are many other choices, all which will require a learning curve and design of new libraries for components.
I have to say Eagle is really good for the price.
