We require targeted "LIVE" Facebook likes/fans to our fan page to ensure we are marketing our business to as many REAL people as possible in the local area. Estimation of 77k people in the area within a 10 mile radius. We don't want any ClickJacking or other extreme measures!
Good honest hardwork and potential for repeat business at a later date.
5k-10k would be a great start... all accounts will be tested so small blocks of 500 or so would be great to ensure authenticity of likes.
