Mega is hmmmmm soso, they more into commercial, sometimes not even fashion commercial + they have money problems I've heard. I wouldn't also advice her to sign up with ANC, it's a very weak agency imo, not good at pushing. Left in the basket are Place, M4, MD. I'd say either Place or M4; I think MD is a good agency but still behind M4 & Place.
M4 or Place hmm not a very easy decision, M4 is very good at booking money jobs, Place is actually very strong in developing books and placing models abroad (they even managed to place a imo commercial model (Katharina F.) with Supreme).... But finally i think she's more of a Place girl....
