This could do.
I just have to get those counters.

The implication of what you're suggesting is that if client A looks up
some address that isn't in the cache, then they will be charged for
that. However, if client B then comes along and looks up the exact same
address shortly afterwards, they'll get a response from cache and so not
be charged. That seems a bit arbitrary.
Why not charge your clients based simply on the number of queries they
make against your resolver? You know or can easily find out how many
queries your resolver is handling in total and how much the WAN traffic
that generates is costing you so it should be fairly easy to come up
with a charging scheme based on the average cost per DNS query.
