Fastest way to make $300-400 a month online?
callmeed: There are some good suggestions here, and I'll chime in on a few things that have worked for me. Keep in mind that I have no experience with adsense or affiliate links.1. I second what peter said about screencasts or ebooks. We've made a good amount of money selling a DVD on SEO for a niche industry. Ours is basically all screencasts and basic SEO knowledge. If you have skills in that area or know someone who does, it can work. Granted, we did physical DVDs but you can just as easily do an ebook or web-based videos.2. Take the BSD-licensed iui code (http://code.google.com/p/iui), style it up, and tie it into some PHP scripts so businesses in a niche industry can create iPhone-compatible websites (i.e. "iPhone sites for plumbers and contractors"). Give them simple install instructions for basic web hosts and it will sell. We've done it and it's worked well.3. Niche industry WordPress themes. We just started doing this and it seems to be working. If you spin it for a "niche", you can charge more than the $30 themes you'll find other places.Hope that helps.
