I don't think they are 'licensed merchant bankers'.

Hope - from your profile - you're asking these days for money UPFRONT for big, urgent jobs from quantities unknown. Let the jobs go if there's reluctance to discuss such terms.

'Financing with a ‘captive’ financier - one that is tied to the manufacturer of the vehicle - can offer an advantage, because a captive financier is likely ...'

'In Italia la Normativa Vigente prevede 2 Tipi di Profili Professionali: 1)PROMOTORI

I am not a native English speaker, therefore I can only try and help you to understand what we mean by promotori finanziari. They are actually the sales people who call on prospective customers to illustrate their financial offerings (funds and the like) in the hope of selling them. I would appreciate if a native speaker could finally provide me with a good translation of the term!
With mandato would mean that they received a mandate from a bank or financial service company.

Today I worked at a conference organized by a major Swiss bank in Milan. The audience was made up of their \"promotori\". I asked them whether they had found a good translation for the term, and they said that either they leave it in Italian or they translate it as \"client advisors\".
