advice for finding someone?

Question:

I need help/advice for finding someone?

I am looking for my Grandmother whom I've never met and my Mom last seen her when she was 8. All I know is her First, Middle and Maiden name, year of birth and obviously my Grandfather was her first spouse. Even though I know she is Cajun and most likely still living in Lousinana, it is still soo hard to find any TRACE of her. Could someone please help me, give me advice. I don't want to spend a lot of money in Family search engines, I would like to look at records for free but again I am open to suggestion.

Thank you all in advance!!!

GenevievesMom, I sent you an email with as much information that I know about her and thank you again!!!
Zabasearch is very cool also (although no luck) and My-moms-kids, you are very right about my Grandmother not being welcoming of us, but I guess its just one of those endeavors that me and my Mom need to go through at this time of our life.
