Freelance PR required for 2 web sites

We are a UK based company running two dating related web sites both requiring PR activity to enhance profile and visitors.

Site 1 - a dating comparison site

This site has been live since 2003 and has evolved from a site just promotion our own singles events to a site which now offers comprehensive comparison of all UK singles events, singles holidays and online dating site comparison. We have good search rankings (currently #1 for “speed dating” in Google.co.uk) which is where all our traffic comes from.
We require a PR person to help raise our profile as a trusted and experienced dating resource, secure incoming links from news sites and more visitors to our site.

Site 2 - a nationwide dating photo and profile writing web site

This site has been live since Jan 2008 but has only had a steady trickle of orders. We are looking for PR to increase public awareness of what is a unique service offered in the UK and as a result increase our sales. We believe the services offered by this site would be good for reader’s offers, giveaways and competitions.

We expect that join promotions could be run to benefit both sites.
