I would NOT buy either of those wigs if you need it in a month. The wig will have to go through customs, and you might not get it in time. I ordered a watch from China once, and it got rejected from customs and they would have had to re-send it - it was $10, so I just bought a $10 one from the US instead. :/
I think you could just leave the bangs as-is. If you wanted more, you could get matching wefts.
I would check out the thread with people posting examples of wigs for examples of the colours. The Red, Dark Red or Henna Red maybe, or the Auburn for a more natural look.
If you look on eBay, I would look for "North America" or "US" sellers only.
