No, it most certainly does not - you can ask for whatever you like and that is your prerogative but there is no reason whatsoever for you to know anybody's personal details, nor for you to have identifiable photographs of them. If you're genuine, you'll be happy to meet them in person prior to them engaging your services.
How you choose to conduct your agency, yes.
How this industry works, no. The people here have many, many combined years of sex industry experience and since this forum is probably the hardest job interview you'll ever have, I suggest you listen to them.
