Website Graphics Needed

I have some existing vector graphics from a print campaign that I need adapted to use on a client's website. Specifically, I am going to need the following: A header for the site that is 980 pixels wide by 250 pixels high; A graphic logo for client's name that is 442 pixels wide by 60 pixels high; 3 blended image graphics (see example) that are 128 x 128. All work must be provided back as web quality .png files. Thanks - Sue
