Need Instagram expert to help with Instagram Account

My 14 year old son recently signed with a NY Modeling agency. We need an instagram account also. I want it to be interesting to potential clients; his first casting call requested instagram link & we didn't have it set up yet. I want to be ready for any future casting calls requesting this. I want it to be interesting and in good taste. Need help. I need someone to assist with an appropriate instagram name; how to organize content & use of recommended hashtags
