Ah yes... The country life... For what it's worth, I live in the capitol city of my state, and we have fewer people here than some places suburbs (hell, we have less people in my *state* than there are in Denver CO alone, at last count). Your age and your location may work to your advantage (I'm guessing you're between 13 and 15). Talk to your neighbors if they have any heavy equipment (backhoes, loaders, skid loaders, etc) and see if they wouldn't mind showing you the ropes, which eventually, may lead to a job doing that specifically, or people will then know you're the guy to call if they have some machine work that needs done and don't feel like doing it themselves. I've had friends that lived way out in the boonies do this when they were younger for a means of income.
Otherwise, yeah, stick to the can thing, and recycling other metals, too. Now, on to the hobby related stuff...
Legend has already giving you some pretty good advice as how to get people active in the hobby in your area, but here's some tips on what to purchase, etc.
Be frugal. Buy the Chaos codex, just so you have the information at hand, and then playtest stuff with proxies before you decide on the, "Must Have's," in your army.
Play some Vassal games ( https://www.heresy-online.net/forums/...splay.php?f=91
straight to the Heresy Online Vassal forums), get a feel for different opponents, a feel for your own playstyles.
Ask questions. LOTS of questions. Ask a question, even if you think it's a stupid one. That, in my opinion, is why communities like this exist--to help those new to the hobby begin to find their own styles and help them gain an understanding of how everything works together, as well as for some of us who've been in the hobby for damn near ever to avoid becoming stagnant, by reading and learning about different ideas/tactics/modeling hints and tips.
To help fund your efforts... Look into competitions. Learn the arts of painting and converting, and then look into the competitions here at Heresy, for example. The top prize for some of these contests are a great way to add to an existing army. Look for local competitions, as well. You might not do real great against the dozens of people who compete here on Heresy (just as an example, btw) for painting or converting, but if your local hobby store has a similar competition, you may surprise yourself by walking away with the #1 slot. I mentioned the painting/converting comps as those seem to be the most common, and they seem to give away models/armies the most frequently, but there are also tournaments you can enter and actually play the game, too.
Good luck in your endeavor.
Oh, and as for getting into Chaos... The more pointy and sharp stuff, the better.
