Looking for Some Excitement?

Then maybe this is the job for you:

Nemesis required. 6-month project with possibilty to extend

I've been trying to think of ways to spice up my life. I'm 35 years old, happily married with two kids and I have a good job in insurance. But somethings missing. I feel like I'm old before my time. I need to inject some excitement into my daily routine through my arm before its too late. I need a challenge, something to get the adrenaline pumping again. An addiction would be nice, but, in short, I need a nemesis. I'm willing to pay $350 up front for you services as an arch enemy over the next six months. Nothing crazy. Steal my parking space, knock my coffee over, trip me when Im running to catch the BART and occasionally whisper in my ear, "Ahha, we meet again". That kind of thing. Just keep me on my toes. Complacency will be the death of me. You need to have an evil streak and be blessed with innate guile and cunning. You should also be adept at inconspicuous pursuit. Evil laugh preferred. Send me a photo and a brief explanation why you would be a good nemesis.

British accent preferred.
