Xuni provides a customised author website (including a PayPal store), and might be worth your while. The FAQ page on the site goes into associated costs. I noticed they also do cover design, and there's a portfolio to get a feel for the kind of work they do.
Need a brand new website, or a redesign of your existing one? xuni.com creates, designs, and maintains author websites for those authors just starting out to those with 20+ books. I specialize in creative, well-organized, uncluttered sites.
