Hey what's up? I am at a loss for trying to find nicknames. For those who haven't read my bio or my debut promo first, feel free to do either of those first, it might help. 
Though as for it is, I am really enjoying EAW so far! Can't wait to be booked!

Poor People's Champion - after reading your bio, what really stood out was the fact that your character comes from a not so well doing family. However, despite all the financial troubles you faced, you overcame all odds and now you are here in EAW. The nickname poor people's champion could be used to motivate those like you against to never give up their dream. You could also add it to your gimmick and take your character into war with people like my character, who is born rich and so had everything handed to him in a silver platter (in case you want one of your promos to be like this, you can use my name). Since you are a face, I think it will be a good nickname as well

I may be the corniest person on this site for this but here goes:

Laura "H.O.V." Laine.

H = Heart because us Faces got to have that.
O = Obstacles because there's always something in our way.
V = Victory is the desired outcome of using our Heart to clear the Obstacles out of the way.

Also, it works with the whole 'HOV Lane' pun on a few levels. You can't be in that lane by yourself and for a Face that other passenger is the Fan. You could relate it to roads/streets/etc and have a whole series of shirts/merchandise using street signs or something.

Yet, still, Hov' is a shorthand moniker for J-Hova aka Jehovah aka God, etc. So there might be something there. You could play around with a halo or wings or something.

I dunno. It just kind of came to me. Probably a stretch/reach but I thought I'd give it a whirl!

Good luck!
