Then, you'll want to train, and you don't need much gear, only a $10 mask and snorkel combo. You should be able to find some freedivers in your area training in pools, though there's much to do before even going in the water. Don't think I'm talking about professionnal freediving though, even casual freediving requires a lot of training for safety reasons, but even so you can actually enjoy what you do. Either you do it seriously or you're at risk.
Tons of freedivers drown. Tons. It's insane. Shit is very dangerous, and most problems are things you won't even see coming, they'll just happen and you can only count on your buddy to save your life.
By the time you do that, you'll have time to think about your gear. And then, you need to try your gear before buying it: your mask should fit your face perfectly and stick without even using the strap, your fins should be comfy and fit your feet, and your suit will depend on temperature and should be comfy aswell. You can't really arbitrarily buy gear, aside from the snorkel, if you even want one.
My only advice would be the Cressi Minima, a great yet affordable mask, about $35 new or ~$20 used, and it's pretty basic and fits most faces.
