It is important to be picky about the photographers you work with. Especially with all the scams, jerks, and amateurs online.
You don't want to be naive about it so make sure you analyze their work and make sure they are professional. And have some credits. Too many times I have heard stories of girls who got scammed or ripped off, never got photos, and we have all been through it, so becareful!
It is better to shoot with one great photographer and invest in yourself, than work with a bunch of no-body,waste of time photographers.
