I don't know if I chose the right forum for placing this thread

If I've mistaken replase it please. One agency suggested me to work as their scout or model agent (is it the same?) First I thought that it'll be easy but then I understand that I know nothing about how to do it

I can't say a girl in the street that she needs trying!!!! I don't know how to do it correctly and politely. May be hear are somebody who already done such work?
