Finding a good marketing consultant

Hi there,

Just wondering the wise way to go about finding a few marketing consultants for my tutoring biz here on the west side of Indy. I'm a one-man show right now with maybe $300 to spend on marketing research, ads, etc..  I have my own plan put together but I'm not confident about the follow through because it's all new territory to me.  Plus time-wise I know it'll be a big chunk.   

Sadly I don't know many other tutors in my area beside Sylvan. Is it just a matter of sifting through the hundreds of names in the yellow pages or is there a quicker approach? Any websites out there where you can customize your search for the type of business you have? Thanks much
