I personally would learn to make money first without investing. Once you accomplish that, scale it up with whatever you need to automate it.
Example: Get a cpa offer in whatever niche you want, look for recent questions asked on yahoo answers about whatever. Answer with something like, "I was able to get the (what they are looking for) here. I highly recommend it!"
Once you get some conversions on something like that, then buy answer assault.
You can do the same thing trying just about any method out by hand first.
