How would I make $700.00 in 12 days? I have a full time job and I do
not want to use any of my own money to get this amount.

1. Sub/letting your apartment and sleeping somewhere else. 

2. Selling stuff you have: car, apartment, tv, stereo/hi-fi, etc. 

3. Selling an organ (like a kidney), if it is legal where you live. 

4. Asking for a loan from friends and/or family, repaying them later,
in long-term period, in which you could make the extra $700.

Please let me know if you accept these and other options as an answer.

Open Microsoft Word

Create a FOR SALE sign

Print sign

Close Miccrosoft Word

Shutdown your computer

Place the FOR SALE sign on your computer

I have a method but unfortunately, you will have to make a $800
investment to get the secret from me. ;)

A friend of mine made over $750 in one weekend with a big garage sale.
Selling unwanted household items really can generate a lot of cash. If
the idea of a garage sale doesn't appeal, there's always eBay.
