Music composition for infants

We need a design of a website with a shop - possible also to make it. The concept is that we compose a unique song to a new born / infant baby. It is for parents and grandparents mainly. The design must be soft, simple and relaxed with nice pictures. There will be 3 packages / products available that can be shown. The band will be for piano, sax and bass. However the price should not be the main catch. It must be possible to listen to a few samples. It must not look like a shop. 3-4 pages. Nice to have will be to see a change of the picture frame and select a layout of the sheet music.
