And this is very much the right website and forum to ask, and far more constructive than your critique, where else do you expect him to ask, his local Citizen's Advice Centre or nearest chippy?
Original poster, thank you for asking the question, you're letting the service providers know there's a need there to be met: I tried a search for unshaven women using the Adultwork search option for unshaven pubic hair, and it only came up with 12 women nationwide, none of them South Asian, much less Sikh.
Maybe you can come to an arrangement with a Sikh service provider to let their hair "lie fallow" for a while and book you first before she trims as part of her routine.
And of course, other members can make their suggestions as to those who may be suitable to approach, exactly what chat in this forum is for.
