i need multiple or continuous sparks.
I know it's been over a year since you asked this, but I thought I'd throw my answer out there in case you haven't built it. Most people use barbecue ignitors, lantern ignitors, or take the sparker out of a lighter. I used a barbecue ignitor, which cost me about $10 at my local hardware store.

Use a long stick lighter and take the igniter out.
You could try a stun gun or lantern sparker.
