Graphics for Website and Sales Document

I require the following items for my website: (I already have the logo) Nice banner to go across the top that will contain the logo and contact details (Banner must be attractive and eye catching and fit within the theme of the website) 5 larger graphics that will appear one after another close to the top of the website (these graphics should describe various aspects of the business that benefit the customer, and each should have a pleasing and unique background, some should include a call to action) 18 small/medium graphics that will server as icons for the various services that are offered on the website (I need the icon version to go on the service list and the bigger version to go into the service description article)
