Brainstorm request: ideas for a professional yet artistic website for electrician

I'm an electrician, my friend is an artist. We're looking for ideas, examples, anything really, to brainstorm concepts for her to create art and me to use it for a website and business cards. We're thinking something along the lines of lightning bolts, dark vs. light contrast etc. but...

The tricky thing is having it be artistic yet professional and without it seeming "corporate." Everything I've seen slants heavily artistic or heavily professional/corporate. Any ideas or examples or any input would be wonderful!

She mainly paints, watercolors, some pencil and pastel...
