i use to do craigslist ads but i got some very seedy customers through there so i stopped. in total i got 3 laptops with "i forgot the password" that turned out to be stolen, one attempted robbery (luckily for me i live in a concealed carry state and was able to fend that one off, without any bodily harm to anyone involved), and one roach infested machine that ended up costing me money to get the damn things out of my house, i opened the case and literally hundreds of roaches scattered out. after that i pulled my ads and worked more towards business customers, pounding the pavement to drum up business and word of mouth referrals. and as far as that goes my biggest clients so far are 2 pawn shops and a local rent to own place, all i do for them are n&p at 80 a pop, between the three i do at least 10 a week, so thats 800 a week for about the simplest work possible. one recommendation if you do that though is with the pawn shops depending on their policies if the customer comes back after it goes up for sale to pick it up they can pay it off so its good to save an image of the hd so they don't lose their data, i usually just have the pawnshops let me know when its sold and then i delete the backup from my storage drive.
