Superyacht boat hooks/poles

This may seem like a simple thing - but I am trying to find a manufacturer of boat hooks about 5m long IN EUROPE ( we have to supply these to the yacht in Palma Mallorca, Spain) with stainless steel hooks at the end. For the bow of a 43m Codecasa. The poles need to be as hard a wood as possible obviously due to the length and we don't want chrome-plated brass hooks as most companies seem to supply. So far I haven't managed to find anyone who can supply exactly what we want. Together with boat hook supports to fix them onto the yacht. We can get the poles custom-made by a carpenter - but we'd rather not do that. But - even if someone can tell me who manufactures the stainless steel hooks that would be a great help!
