Baby modelling help please!!

Hello I am new to mumsnet and was really hoping for some advice. My little boy has been accepted by a few agencies and I was just wondering if anyone has any experience of any of these as I'm not sure which one to go with. The agencies are:

Mim
Ology kids
Tuesday's child
Dk models
Scallywags
Bizzy kids

Thank you
