Update of Logo for Digital Forensics Company

We need a new clean, crisp logo to add to our website http://www.digital-detective.co.uk.

Digital Detective

We quite like the font that we currently use for the logo but feel we need something else in conjunction with it. Ideally, it would need to work as well on a black background with white writing as well as on a white background with dark blue writing.  The logo needs to go on the top of the web site which currently has a black banner.  It also needs to able to be used on company paperwork.

The company deals in digital/computer forensics software, training and in the future we will be doing computer/mobile phone and digital forensics.

- We like this current logo http://www.digital-detective.co.uk/…llLogo.png using a font we have.  It would be nice to have some sort of logo as well as this format or style of text.  The dark blue is RGB 20,29,76.

Something reasonable simple and not too fussy or complicated

We would possibly be willing to look at alternative fonts etc

- We have had suggestions with magnifying glasses, images of detectives heads, detective and sherlock holmes type logos in the past which we do not like
