Design a website, with ecommerce processing for 4 services (no physical products)

Need to design a 5-6 page web site (main page, services page, about page, FAQ page, Contact us page), with 4 products (4 services to be purchased via credit card, so no physical products), using bigcommerce.com, godaddy.com, or yahoo small business (possibly wordpress, although i'm not as familiar with it). thus, need to set up ecommerce processing and gateway (i already have Paypal account ready) for the 4 services, i.e., paypal's website payments standard. havent decided on which hosting service, hope you can provide suggestions on which is best for the website i've described.
