It will depend on how much shooting you're going to do. I cast and shoot over 10,000 bullets per year between my wife and I. For us, it's a huge savings, but then I've got a lot invested in casting equipment, but have accumulated it over a long period of time.
You can spend as little, or as much, as your heart desires, depending on your needs. You could get into it with a simple casting pot and small casting ladle, plus a mold and some simple sizing and lubing equipment, for probably around $100.00+/-. Or, you could go into it whole hog and spend a couple of thousand on a Magma Master Caster, a fully equipped Star Sizer and a few molds.
It all depends on your tastes and requirements. If you know anyone locally who cast bullets, that would be a good place to start. If not, then the Lyman Cast Bullet Manual would be a good start, too.
You can also go to castboolits.com and get yourself completely confused on the subject, since your knowledge base appears to be zero. But then, we all pretty much started out like you are now, only some of us before there was an internet. Like I said, it can be as simple, or complicated, as you like.
Hope this helps.
