There's no way you'll be able to buy any equipment of any use for $200. Your best best is to find some enthusiasts in your area, join club or whatever, and you'll be able to get it done for next to nothing. There are always guys willing to work for free or a crate of beer, it's a good networking opportunity for all, and something for the showreel. The bonus there is that these guys tend to have their own equipment, or cann borrow it, or you can rent it cheap enough.
Spend as long on the planning as you can. Have meetings, plan shots, discuss everything, arrange your locations etc. You can't plan enough.
