To write and distribute Press release

Hi
I need a press release with original keyword rich content too promote a band that performs at weddings in the North East.
I also need to press release to be distributed amongst good PR sites.

We are a one stop shop providing an award winning band, DJ musicians for reception etc.

I must emphasise this job is to write and distribute to help with our SEO. I would like to see examples of various relevant sites you would use.

Thanks.
