Salesforce.com Visualforce Page Creation

We are a [login to view URL] customer and have used the customer portal module to allow our customers to obtain information about the products they purchase. We would like to have a custom visualforce page to be used as a tab within the [login to view URL] customer portal. The visual force page will need to dynamically display content based on who is logged in. Using the current logged on user, the visualforce page will need to query and display the following elements: Portal user's account Then using the Account name/ID it will need to query and retrieve 3-4 fields from assets associated with the account. Using this data the visual force page will use these parameters to concatenate some simple HTML with these values. that is it for this first phase.. We have a second phase where we will use the portal user's role to control if the logged in user can see all assets for the account for which they are assigned or just assigned to the contact. That is not as important for this first go. We requires someone who has done [login to view URL] and visualforce page development and has either a portfolio example illustrating this work or a reference that can testify to the type of integration.
