Model template ideas

Hello guys, just a newbie here, I just wanna ask for some help. I have a client, KC helicopter , who requested me to do a model template for them, for their plane. This would be my first time to do such and even though I have some ideas I can't lose or give a bad impression to this client so I thought I'd ask for some help from the pros. Can anyone here give me more ideas? Thx in advance
