Any software tools to make double-sided circuit boards?

[Joyce Taylor]

[SIZE=10.5pt]I have made a PCB [/SIZE][SIZE=10.5pt]for a long time,[/SIZE][SIZE=10.5pt] single sided and everything was done by hand.  Fast forward to today, and I have several clock circuits I would like to have double-sided boards made for, and I have a pressing project that will require me to finally jump into the water.  I bought a vintage unbuilt Heathkit GC-1000 clock kit, and two of the circuit boards are missing.  My applications will all be less than 10 KHz circuits.[/SIZE]
[SIZE=10.5pt]The circuits in question will have DIP's of various sizes, some surface mount components, nixie tube sockets, etc.  I don't mind laying all of them out by hand - I don't believe I need a program that automatically does the routing.[/SIZE]
[SIZE=10.5pt]The first board I need to have made is shown in the attachment - foil from both sides is shown.  The board is about 2.6" x 6".  I use Photoshop for various graphics design, but my guess is I need a custom piece of software that manages multiple board layers, trace routing, hole sizes, etc.  I have no idea where to begin, or what kind of output file I need to send to a fabricator.  Any tips for approaches would be greatly appreciated.  [/SIZE]

This is a rather complicated process, you will have to look for it.
