It's always funny to see how so many ppl are quick to lash out at a newbie or anyone simply trying to come up.
It's true $5-$20 bucks isn't much at all, but that doesn't mean you can't make any money.
In fact there are lots of ways you can make money from even zero, it just requires some effort (reading , researching forums/web etc.)
I'll give you one:
Search for Tumblr and/or adult methods on here.
if you're not into adult content, the same methods can be applied to anything that is a popular web niche or has a dedicated audience of ppl.
After a week or 2 of solid researching and studying make your first investment, (this will cost you less than $3) on a domain and web hosting.
Spend 50 cent at Register.com or 99cent on a Godaddy domain special
grab hosting from Hostgator for a penny the first month (choose the baby package)
Take the $100 in free Adwords vouchers and use those towards non adult campaigns and or sell them for $25 (or whatever they go for currently) use that towards further investment on proxies down the road.
Push traffic from any social web 2.0 property you have created (by now you should have several from several sites : FB,Twitter,Stumble,Redditt, Tumblr,YT, etc) to your money site (preferably a Wordpress site , but honestly it doesn't have to be. I have several simple one page .html sites that make a min. of $500 a month on autopilot literally...)
Many ppl resent ppl who aren't willing to research for themselves. I too don't like it.
Although, I also don't like ppl who have conveniently forgotten that they started with zero knowledge as well, but love to come off as if they always have.
Never mind haters, handle your business and keep pushing.
*The absolute BEST investment you will EVER make, will be investing the time to learn, read, compare and APPLY.
If you don't study for yourself YOU WILL NEVER know, nor will you know what to do when the tides change on you in what ever method you decide to take up.*
