I would recommend Wildcatseo www.wildcatseo.co.uk for search engine optimisation and online marketing although based in Scotland they offer services to businesses throughout the UK.


On their website they have some FREE SEO tools for you to check your own site, I frequently use page rank and link popularity checker tools "http://www.wildcatseo.co.uk/tools.php


Here's my recommendation in return I'm looking for information and recommendations of companies that deal specifically with osCommerce websites.
