Considering a $3000 loan for Facebook ads

Hi guys,

I used to be in the Facebook viral business and made £400 a month, however the guy I worked with was greedy so we stopped.

I'm now looking at getting back into social media to build my fan base / likes.

I am considering getting a 3000$ loan and pumping it into fb. What's the best or most profitable way to gain organic engaging likes quickly? I know I can make $400 ish of 100,000 likes that are organic and engaging.

What's people's thoughts?
