Some Ideas for Making $5000 This Summer

I've been thinking about how I can make $5000 quickly, unfortunately with my ideas so far I'm going to be knee-deep in grumbly poker players in a few weeks :/

• Remember that movie War Dogs?  Apparently bidding on government jobs is a thing.
• You can get $1200 if Dish Network ever called you (unfortunately I don't remember if they ever did or not).
• I looked through the list of class action rebates but don't see anything I qualify for.
• I've been looking through the entrepreneur subreddit...but nothing jumps out at me so far.
• And by Googling 'how to make $5000 in a month' I came up with this, this, and this (apparently I'm not the only one wanting to do this).
• There's always busking...
