my favorite method is pay someone that knows what they are doing theres plenty of people here who offer that service. i'm no software expert however senuke has a feature that lets you check the viability of targeting a keyword, and i've heard market samurai is very good for this too.

Thank you.. I did think about outsourcing.. Sometimes the budget doesn't allow it though :-)

Yep Outsourcing is a great way. =) There are tons of people who could do good keyword research.

Try going to Fiverr ? The place for people to share things they?re willing to do for $5 - People would do anything for you for just $5.

I am a big Market Samurai fan myself.
