Backlink creation and other ways to improve site visibility

I run a small research consultancy and had employed a SEO freelancer to popularise my site, as well as paid one of those automatic submission sites to blast my details to thousands of sites and search engines. In combination they have worked well for us. We are already on P1 on google for many keywords - but for a few kwywords we still dont feature, as our earlier selection of keywords did not feature 2-3 important keywords. Now I need someone to : Create backlinks on specific advertising, marketing and research sites and blogs - mrspace, mrworld, adworld, etc Similarly porst our details on sites linked with Dubai and middle east - e.g. ameinfo, Post a press release globally any other ways to boost our rank - just for those missing kew words As you will see if you are awarded the project, most of our SEO work is already done - just neet that small boost for a couple of keywords Cheers and happy bidding
