Where to Get Charging Circuits other than from Disposable Cameras?

After a month of procrastination, I finally got myself to make a coil-gun by choosing it for a science project. I am going to go to nearby Walmart, Radioshack, etc. for used disposable cameras, but it is unlikely I am going to get them. Since I am pressed for time (2 weeks for creation and experiment), I figured I should just post this now. I know I can get capacitors, but what specification should I look for?( around 400V give and take) Also, I need charging circuits ( or another method to charge it with) but don't know where to get them. Since I am pressed for time and still am a novice to electronics, somethings like a DC to DC HV converter would take too long with my amount of expertise.

Please help and Thanks in advance
