If you are really serious about doing something properly in IM, then you are welcome to mail me @ email@example.com and I will set you on the right track for free.
Tell me what your possible niche options are, and I will do your keyword research for you and even confirm a product for you to promote.
What you might not realize yet is the set up of your business does need to be done 100% correctly - BUT the real test is if you are prepared to then knuckle down and do the articles day after day, add the videos day after day, add the back linking etc. it is that initial period where nothing happens for a week or 10 that most people give up, and then say that it does not work.
tell me a bit about yourself, how much time you have , your interests, if you have any money to put into it (not for me - but hosting, domains, stuff like that)
