To me a frame for a photograph should be simple and functional and not at all ornate. When it comes to framing, I like a simple black frame. When it comes to an online presentation, I was also looking for simplicity. With that approach, I was very happy to spend a minimal amount of time and to produce a Zenfolio site that met my needs.
You need to think about what you want in a website and why the current template fails to meet your expectations. Once you really know what you want you have lots of options. First you could continue with Zen or another provider with a similar template approach. You can experiment with different templates and use different templates for different areas of you site. Even with my simple website, I got stuck and dealt with the help desk both by email and phone. I got very good responses. You might try working with the help desk.
You can also go to Word Press or another provider which allows greater freedom in design. Of course, you will have a much steeper learning curve. You will need to invest lots of time and you will probably also end up using predesigned templates. If you are going full bore commercial you probably want to hire a webpage designer. You can spend as much as you want and give the designer as much or as little freedom as you choose. You can also get help with registering your site and with search engine optimization (SEO) techniques and with promoting your site and your business.
I cannot be of much specific help with your current test site. I have no idea what you currently know or care to know about website design. I am not sure what level of critique you expect to get from this forum. Trying to get "tips and tricks" for website design is likely to work about at well as if you asked for the same sort of information regarding photography.
