How about this one: sell 30 days of your life for $100+ US each, be ready to do ANY work you are asked to do each day by the buyer (no matter how disgusting or hard it may be), that's the deal: one full time worker for 100 USD/day, willing to do anything that's legal and not offensive.
Get a web page 30daysofmylife - allow people to purchase days for $100 US each. Then start promoting BIG TIME (local newspaper, radio, tv, twitter, facebook you name it).
You don't need a fancy website, just make it a redirect to ebay - so that you can directly sell "your days" there - reserve price: "100 USD" each.
Don't be shy about it, tell people that you made financial mistakes and that you need the money in less than two weeks now and that you are willing to do whatever needs to be done each day (work wise). Heck, probably you could even get a TV channel on board to pay for stuff.
Also, get a blog/vlog - make sure to actually write about everything.
If you do this right, you will probably make MUCH more than just $3K ... with sufficient media coverage, the blog alone will probably make more than $3K per week using just adsense. Also, you could even write a book about the whole 30 days in the aftermath...
