hey nice post, and good attitude little guy. You will do great
Anyway back to the topic, i would say like this. settle down on one blogger for start and start making good manual reviews with keywords and photos in it. Must be relevant and also unique. Later on, with your money, buy your domain and you just move that blogger to a hosted wordpress website (you can migrate without loosing traffic, there are a lot of tutorials for it). Get social, make facebook, twit, g+ account for your blog, make a brand ( a easy to remember sub domain that will be later be similar to the domain you will purchase later), create a logo, get some twitter feeds (post automatically from rss to twitter and facebook) , stay constant. make a cool youtube video about your website. Anything you can think of to get that exposure. Use traffic exchanges services like easyhits4u to get some initial boost.
It will be hard to do all of these but once you go up using this methods, its gonna be just watch and cash in! If you need some help just pm me, i started as young as you and i know how it is to get a good advice.
Best of luck!
Thanks. I'm not really working with PPI anymore, mostly my social media service site.
