need night sights installed on 870 in Cincinnati

[p4+riot]

I just bought a Remington 870 Tactical and would like
to get some night sights put on it, specifically these:

Unless someone can suggest better sights.

Does anyone know of a reputable place to send my shotgun to
or know of a good reliable gunsmith near Cincinnati or Northern
Kentucky?

Thanks,
