Not to be a downer, but high end web sites and internet applications is my industry. $5000 is very low. You could get the designs (mock-ups) for $5k if it was a very basic site without any special requirements, but no code. When you use words like best high-end, even for a simple site the price range would start closer to $60k all in.
Are you sure you really need high end work? It is usually reserved for companies that have unique needs.
I agree with segedi, an off the shelf site with some css tweaks is more suited for a simple photo site.
