Complete the Improvement of an existing website

The work is almost completed website. Need to improve my existing website to make it appear more professional and upload some updated pages. The provider needs to have done work in enhancing corporate and individual websites. Understand branding to target at senior management. Interested providers, please submit relevant work done. I will supply all the contents and the provider merely need to put them together and re-write for maximum impact. I am looking for a long term provider to enhance my other 30 websites if the provider does well on this one.
