Take Instagram like picture of yourself holding a sign

I am promoting an app on instagram, and I need picture of a female holding a sign. The picture needs to be boxed, like on instagram. Ideally I would like I need the picture to look "real", as in it should just look like another pretty picture on instagram that your friends would post, I don't want it to look commercial. All you have to do is take the picture and then email it to me. I was thinking the picture would mainly just show the females face and the sign, the words on the sign must be very visible. The sign will say this: "I used the Insta Pro App to gain OVER A MILLION followers on Instagram -lol_vines" Please send me some face shots or more preferably, images that you have made or taken that look "good" on instagram.
