Opencart store / theme customization

I have a clean Opencart store installation. No data, no theme, nothing.

I want you to make it look good. I'm flexible on what that means, but it shouldn't look like every other store in the world.

I tend to prefer simple over complex in terms of visual design. If you're a graphic artist and can make your own logos, even better. I'm open to purchasing a base theme to use if you prefer to go that way. (In fact, I have one already, although it is not installed.)

I will work with you and provide feedback as we go, so there will be no surprises.

Timeline is 3-4 weeks.

If you are a very good Opencart developer, but not a great graphic designer, I'm open to hiring a graphic designer separately to work with us. However, if you can do both, even better.

Please send links to stores you've designed, or other evidence of your experience with Opencart and/or ecommerce generally.

Here's a couple of simple online store design I think look good:

However, we are not constrained by these. I am open-minded.
