wordpress blog needed

Hi there, I need a customised wordpress blog. I have a free one at the moment http://fabulousmasterpieces(dot) wordpress (dot) com but really need an upgrade. I haven't yet found a premium theme i like either hence the need for a customised blog. I'd like it to be clean and simple and have a slider. I'd like to show artwork and articles on art news and biographies on [login to view URL] a portfolio for all our recent oil paintings. I don't have much technical ability so it would have to be really easy to use. Also i'd like to put testimonials on that keep rotating and a contact form and have a footer. I'd really like someone who is a native english speaker and has done a lot of wordpress blogs before. If you could show me an example wordpress blog you've done that would be great.
