I represent DN Invest Ltd. We can offer our services if you find them useful. You can learn more about us at
www.dninvest.co.ukThe Premium Domain Brokerage service might be interesting to you (
http://dninvest.co.uk/premiumdomainbrokerage.html) if you plan to have premium domain and want to acquire it at the lowest possible cost.
Our Domain Consultancy (
http://dninvest.co.uk/domainconsultancy.html) includes SEO consultancy too.
You did not mention your budget, but if you are serious about your project and have appropriate budget we can save you a lot of money which you would need to spend on marketing if you start with bad domain name. Sometimes is cheaper to pay $1 million for domain name than to use cheap and "cool" domain as you will need to spend multiple millions to achieve the same results as you could with premium domain.
Please don't hesitate to contact us to discuss how we can help you. You can use the contact form at
