Stand out, powerful but rich and elegant logo required.

I need a logo to be used on our new website, emailing signatures, Word and PowerPoint.
It needs to be very positive, powerful and elegant.
Company name is Positive Presence. Strapline is 'taking the best to be the exceptional'
We are known as 'the intelligent consultancy for intelligent people' and that describes our market - traditional sectors like law, finance, banking, pharma and all the professions. Not start-ups /tech companies unless they are FTSE 750.
We also need need a 'By Laurel Herman' which will be incorporated into the logo when relevant.
As space is always at a minimum when I the logo is used in doc headers etc., It mustn't be too wide or too high. I like the idea of using the P in the People and the P in the Positive in some way clearly and strongly linked. By the way, I like angles but I do like curves incorporated!
I have uploaded the previous logo but it was designed 25 years ago and it's time for a change although it has done the job!
