Try getting some information into local colleges, universities and larger workplaces where there is a good ethnic mix and try speaking to the elders in the temples and mosques.  It may also be prudent to speak to editors of local media before sending in a media release promoting the need for ethnic audiences.  Identify ethnic radio stations and call their Programme Controller and new team before sending in a media release.  Phoning first is a courtesy which might open up a relationship and increase the chances of being covered.

 Also, seek out any ethnic magazines and websites, get in touch asking them to put in an appeal for your ideal audience mix.  The following sites should prove helpful in your research of appropriate radio, tv and press.
