I can't help you with a guide for doing it, but I will suggest that it's not going to be fruitful. At all. Unless you have a warehouse full of video cards all to yourself and hashpower exceeding 5% of total network...
What would be considered fruitful? I have ~9Mh and make about 7 coins a day, which at 60 cents is $4.20. Just trying to get a feel for what most people consider fruitful.
