I like the hours involved as I'm pretty lazy. Picking people off with a snipers rifle won't really worry me either as long as the money's right. I used to squash insects as a child so it can't be that hard.
How do I get a good customer base? Should I just work 'Probono' to start and pick off people who others dislike in the hope of something later?
Or are there any Embassies near you from ruthless countries?
I've tried google and Yellow Pages, found nothing. All I found under 'Extermination' was rats and wasps and that won't pay much.
