I need a professional website designed, preferably through wordpress (if possible)

Kind of design: Custom website
Num. of web pages: 5 - 10
Description of every page: The site will include:

home/landing page
About page
Contact us page, with submission form
Case studies page
Existing client page, to include
- Client Brief (just editable text field)
- an ability to upload pdf documents, where the front page of each is visible and can be clicked and opened
- an interactive google map, for each client.
- an ability to view current status of account and make payments where there may be an outstanding balance.
Ideas for the visual style: simple and elegant, thinking along the lines of a boutique hotel/high end retailer. the brand logo will be the strongetst element of the landing page.
Things to avoid: cliches, gratuitous pictures (would prefer art work/photos to be original and not purchased from the web)
Website information: we are a high end, boutique london property consultancy.
Urls to draw inspiration from: thewhitecompany.co.uk, tedbaker.co.uk, hamptons.co.uk,
Extra notes:
