Web Design and Optimisation

Hello,

I need to design and launch a new web site. I currently have 3 running which i have designed myself badly. I need to incorporate all three into one.

I am looking for ideas but I do have a few ideas myself from other web sites i have seen on the web.

Important things for me
- Design to be very high quality as aimng at corporate UK end users
- Want to be high up in Google and other search engines.
It isan IT company

I will also need to add updates to the website say every 2/3 months

I would like to start this project within 1 week.

Thanks
