Cost of Wholesaling in the SF Bay Area?

[Sasha Josephs]

Hi! I am doing my research on starting a wholesaling business. I'm located in the SF Bay Area and am curious if anyone out there in the BP ether would be willing to share stats on how much they spend on their marketing per deal? 

The goal would be to have two deals done next year, and idea is to handwrite letters and mail them to a driving for dollars list I've generated over the years (~200 leads on this list). I'm also willing to handwrite to other lists (tax delinquent, high equity, probate, eviction, etc).
