Homebrew PCBs

Good day all! I was wondering if anyone here has much experience with
PCB design and layouts? And may be willing to help me or at least 
guide me in the right direction?

I am looking for some help in designing a layout for a personal
[not for sale, home use only]Colloidal Silver generator. Which, 
through a current flowing through a .9999 pure Silver anode and 
a .9999 pure Silver cathode while both are dipped in a high quality 
Distilled Water, disperses silver ions into the water. The amount of 
silver in the water is measure by parts per million (PPM).

In a nut shell, what I am wanting it to achieve is 1)recieve/display 
a signal in mA and in PPM prior to starting 2)push button start which 
also starts stirrer (agitator) and lights a red LED 3)switch polarity 
of the electrodes every 60 seconds 4)reaches set point value for PPM 
5) auto off which also stops stirrer (agitator) and switches off 
original red LED and lights green LED. I was tinking about using 
about 9 volts AC as the power source.

Thanks In Advance
