Logo for a Project Management Consulting Company

Clean/Simple
Sophisticated
Modern
Abstract

Apple green or perhaps orange? Something that looks fresh, likely combined with grey.

not sure

The logo could in some way represent the scheduling component of project management (Gantt chart) as a further play on the term "Lead Time" which is a project management scheduling concept.

Here is a link to a video explaining (graphically) how lead time is represented in a project schedule: http://office.microsoft.com/video.aspx?assetid=ES010274798&vwidth=1024&vheight=768&CTT=11&Origin=HA010156787

I had thought of combining the L and T of "LeadTime" into a gantt chart type representation (project scheduling) or including a diamond shape typical of project milestones in a Gantt chart. But, I don't know how to make a diamond "cool", so would prefer to omit the diamond shape if that makes the logo feel stuffy or old school corporate.

I'd also be happy with a completely abstract, more generic logo, that sends a message of professionalism, sophistication but doesn't necessarily convey "project scheduling/management". I don't want the project management message to be too strong in the logo, since the company may also do more general business/change consulting.

I will be associated/sub-contracting to this company: http://www.longviewsystems.com/ so the logo needs to be substantially different even if it uses the same colors (green) and similar letters if the L and T of LeadTime are incorporated into the logo design.

I would like to see the logo cleanly separated from the words "LeadTime Consulting" so that the logo is a small image that could be used with an email signature: i.e: sometimes the company name/logo would appear together and sometimes just the logo without the company name.
