I need to make ~$75 a month

I run a few whitehat sites and I'm not monetizing them very much, and I'd like to keep it that way. However, my parents want me to start setting aside $150 a month for college funds in the future (to pay off my student loan), but of course, as a teen, this is kind of upsetting and I want to offset it as much as possible. =P

So for now, I'm aiming to earn back half of what I set aside via blackhat sites or methods. What is a good way to do this that requires minimal investment? Would HaRRo's thread be a good start?

I'm also thinking of offering text advertising on one of my whitehat sites, but I don't know how effective it would be, so I want to get started with other money-making methods to keep my income from dropping.

As for my current websites:
One site already has PPC ads with Affinity, which for me has performed better than AdSense. Plus my AdSense account was banned about a year or two ago, so I'm trying to get back with them as well.

Another site is my business site. Don't want ads there.

And the last one is a new site, which is not ready to be monetized.

There's your answer bud.

First off, never get a college loan. And you could easily make 75 a month writing articles for assiciatedxontent.

Try to add some adsense or any other ppc ads, and drive more traffic.

lol...what is this "i got the traffic and im not making any money BUT id like to keep it that way!" wtf? if you want to make money, monetize it

First if you have traffic on your sites monetize it.. Put up the adsense..

What you can do? If you can write you can write articles for people... Same for seo or design.. Depends what are your skills..

Go to fiverr and look around to get some ideas and put up your gig...

I don't have boatloads of traffic, but regardless:

That being said, I am open to creating new websites. I looked at http://www.blackhatworld.com/blackhat-seo/making-money/248837-make-1000-per-month-autoblog.html which seems reasonable. I'm sure I won't make $1000 a month, but it's a start.
