Reactive8 Emergency Services

Logo Name：

Reactive8 Emergency Services

Company Intro：

I need a logo creating for a new business called 'Reactive8 Emergency Services'. It's a new website that provides emergency plumbing engineers to jobs that people and businesses post online. I'm hoping to expand into other trades so I don't want anything plumbing related featured on the logo though.

Instructions：

I want it to look high end, premium and quality, perhaps a crest with the word reactive and the 8 through the middle. I like the colours blue and yellow but I'm not set on these colours and open to other ideas.
