I can't recommend any product creators, but i would say you could do your own research pretty easily. If you're getting into the IM market then i would target all the frustrated newbies. Here, the newbies just want clear, concise methods that they can easily try - with clear step by step guides. They don't want to be overwhelmed with the whole knowledge base. But anyway, a good level of research can be achieved using askdatabase.com and driving newbie traffic to a landing page asking them what their main frustration is with their IM achievements thus far - you will probably have to incentivise them to leave an answer (plr free guide would suffice)
Boom! automated market research. analyse the frustrations and create a product that solves their problems. captcha their emails also - you know the rest...
Paul, if you found my suggestion helpful at all i wonder if you would return a favor - i'm currently looking for a resource where i can find continuous forex product launches (just thought you might know, and save myself some hunting)???
