30 khz bandpass filter

i wanna design a bandpassfilter on a FR4 pcb 1.6mm
thickness.The range is between 70Hz and 30kHz.Cutoff frequency at 200Hz and 10kHz.
Pls advise me what type of capacitor to be used as listed below:
1. 220nF
2. 100nF
3. 470uF
Is there any strict rules to make a good design during layout a PCB?
 

For this frequency range you can build an active bandpass filter based on opamps.
You will need two filters connected in series: lowpass and highpass.
I hope you have a calculator, so here is the design and formulas:
**broken link removed**
FR4 uses up to 8 layers, but I think can do it on 1 layer - max 2..
Regards,
