Photographers do reach out to prospective clients and TFPs - it's not uncommon at all.
It is however far more commonly the reverse with clients reaching out to photographers.
That said, your instincts do you credit as the photographer that reaches out to the client/model can be somewhat sketch and deserves to be very carefully vetted.

No professional I know of would ever even think of doing that. We're all too concerned about getting sued or accused of something we did not do.
