The key question is "are you an ISP?". If the answer is yes, then the
IPv6 equivalent
is a /32 block. If no, then it depends on whether more than one site
is involved, since
the allocation size would be a /48 per site.

IPv6 is a combination of classful and classless addressing. The result
of that is
that all allocations are sized to be more addresses than you could possibly ever
need in the majority of cases.

You fit under "Direct assignments from ARIN to end-user organizations" and
should have no problem getting a /48. If you need multiple sites then
"IPv6 Multiple Discrete Networks" would apply.
