I need some quick money-making schemes.

Alright, I'll try and keep this brief:

I work as a sound engineer, and since it coming into the holiday season, I've found there's a lack of work floating around. I'm not gonna be a sponge and say "SEND ME SOME MONEY PLZ KTHXBI", but I kinda want to keep on keeping on.

So: What's some good ways to earn a decent amount of money in a short span of time? Here are some things I've considered.

• Prostitution (I'm an average looking straight male. Not much I can do there)
• Holiday retail (I'd prefer not to, mainly for my hatred of teenagers)
• Selling drugs (This tempted me the most, but I'm lacking starting capital)

And yes, I am actually attempting to make money the old fashioned way. I just wanna try something a bit different.
