Can anyone provide a site or advice on placement a details of construction
and
design of spoilers?

What do you want the spoilers to do? Glide path control like a sailplane or
slow an airplane down to flap/gear extension speed? If the latter, look at
some Mooneys with speed brakes. If the former, visit a gliderport. There
are lots of variations.

One thing to keep in mind is that spoilers spoil the lift in a way that
redistributes it spanwise towards the wingtips. On sailplanes, this can
reduce the wing ultimate load factor from, say 5.5G to 3G - not a good thing
if you are recovering from a dive.

Some people have even tried them as alternatives for ailerons - lots of
issues with this.
