Internet Marketing Strategy/SEO/Web Content/Linked In Social Media

We are a business and risk consulting company looking to launch our website by next week and to start an aggressive e-marketing and social media campaign.
Essentially, what we are looking for is someone to help with the following:
1. Help us finalise the website for the launch: by understanding our business and key messages/objectives – Review copy and advise on optimising layout and structure
2. Develop a marketing strategy and campaign – a crucial understanding of our market is a must: carry out analysis and come up with suggestion on how we can differentiate and push our brand.
3. SEO optimisation through articles and blogging: we already have people working on articles for the website: content review is needed
4. Social media marketing using linked in – this is where the focus is right now

We are working towards a tight deadline, and would love to hear back from you by Saturday this week

Thank you
