What are some tips you can give on how to market a charter business?

I know business cards and website are a must but what other avenues have you all used that produced results?

I know from previose business experience that word of mouth is my best advertisement. I also know it will be a long haul in building a charter business. Im not looking for overnight results.I still have my other business I am not giving up thinking I will be an over night sucess.

Thanks for any input. PS Im very thick skinned so all input is welcome.
