A-List high end personal concierge

The company is set to be very high quality. We need the clients to have membership login and request services just as [login to view URL] and dreamweaverconcierge.com. We would like the clients to have the ability to detail request on grocery shopping as grocerywiz.com. The user accounts should have the ability to be personalized with family details, personal interest, doctors names number, contact list etc. I need someone very detail oriented to develop a sleek highend design. The goal of the project is to provide the clients the ability to give request through the site and to make them feel exclusive to be an member. The site should be secure to hold sensitive client information with the ability to pay for membership, fee of services and copy of previous request receipts. Most important is the upscale feel of the site and client account capabilities.
