Although procurer has these meanings प्रापक, प्रापयिता, समाहर्ता but I think that दलाल is applicable in this case.

Procurer is the person other than the pimp and the trafficker. He or she can be the owner of the brothel or the end-user of the commodity i.e. an unfortunate woman termed sex-worker by the rotten "civilised" people whose boss is Bush, Manmohan, Sonia, etc.

That's the Hindi word for it in the given context.

I'd translate 'pimp' as 'भड़ुआ'. Even though the terms are close, I think the term 'pimp' has the sense of controlling the prostitutes as well.

Taking the reference of the text quoted by the asker, I have used a different hindi equivalent for 'procurer' which is very commonly used in the sex trade. As the words 'pimps' and 'procurers' have been used in the same text so it would be helpful for the translator to use different equivalents in hindi. I feel that 'Dalaal' should be kept reserved for 'pimp'.

As the word 'procurers' is plural so the translator should change the hindi word as well in plural which would be भड़ुओं.
