Talking of opto-isolated relay board.  Have you had chance to start
looking
at the design and work out the approx. cost yet?

If you do and plan to relay control it from something computer related
be
aware of back emf and its effect on the control circuit. Opto-isolate
if
poss or add shunt diodes or whatever they are called. Saves you
resetting
HV every night (as happened to me) or worse.
