Need SEO Company URGENT

We have a number of different websites that we would like to drive traffic to. As an example, we have a property site for people who need to sell their home quickly for whatever reason in the UK. Good search terms are 'sell home fast', 'sell home quickly', 'sell house fast' etc. We mostly use paid advertising at the moment and are looking for someone to take responsibility for driving organic traffic. We aim to be getting at least 100 targetted visitors per day within 3-4 months and are looking for someone/some team to do a trial for a month or so on 2-3 keywords to see if they can drive trafic. Please let me know if you feel you have the expertise to do this, if this would be on interest to you and what your salary expectations would be. Thanks,
