Engineering Firm needs a logo design

This is what Juapi Engineering, PSC was looking for in their logo design

The company will be initially offering electrical engineering services (renewable energy projects, electric system design, project management and administration, and permitting), but as it expands it will offer services from other engineering branches.

Slogan: "More than engineering"

Colors: I am open to all colors, but I prefer blue (dark and royal), black, grey and white.

I would like the logo to look professional, presentable, clean, modern, and stylish.

Also, a symbol that would represent the company would be a huge plus.
