Twitter is good for driving real human traffic, not to sell typical cpa and affiliate offers.
Nobody thinking about promoting local shops, cafee's, stores, clubs. Mixing online and offline marketing can be much more lucrative than few clicks of 0.18 here and there and setting goals "dollar per day".
Something like this is very doable :
-Local cafe or club doing promotion of new type of Vodka.
-Go there, approach to manager or owner, ask how much he will value new 500 or 1000 guests for that night. They are doing various promotions every weekend so they already know how much people is usually coming on those days and they will know the difference, see and appreciate new customers, for sure.
-Use your TweetAttacks or other Twitter tool for collecting users ,making followers or whatever and prepare highly targeted usernames (search specific users from that city and location, search tweeter accounts for other popular clubs, cafees, restaurants in that city and collect their followers etc)
-Use your favorite way of tweeter marketing to tell them for Vodka promotion in that club.
-If successful, will be more jobs like this, all those managers have a lot of connections and friends with similar clubs and businesses. If not so successful, tweak here and there, take more time for collecting good followers base...
