Write a press release to promote our stand at a retail show

We are exhibiting for the fist time at Spirit of Christmas fair in Olympia London, would like to submit a press release to the PR company promoting the show. We could talk about finally a solution to nice bins - up until now we supplied mainly to the trade. Also, we are launching a new website early September. That will bring my press releases and copy writing. My business is MustHaveBins.co.uk.
Have attached a couple of file for background to who we are and our brand style and new site layout
